Two alternatives – X500 and NotePAC-III

If you need a portable laptop-style computer with an expansion slot or two, there are not many options…. There’s the Portexa NotePAC-PRO and the Getac X500 Server. In this article, we will look at the similarities, differences, and suggested applications. Disclaimer – we cannot sell Getac X500’s – but this will attempt to be fair and unbiased. Members of our staff have extensive experience using and modifying the Getac X500 and have a healthy respect for it.


Both systems are large portable laptops.

The X500 (Launched June 2011) is 16.1″ x 12.6″ x 4.6″ (933.2 cubic inches) and the NotePAC-III-PRO-V (Launched February 2019) is 16.75″ x 12″ x 4.5″ (904.5 cubic inches).

The NotePAC of course does feature a triple display monitor, so it’s not quite apples to apples.

The NotePAC-PRO has two PCIe expansion slots as standard, whereas the X500 is expandable using a ‘slice’ that replaces the bottom cover (the dimensions listed include the slice). The X500 slice can be PCI or PCIe, so if you need to support a legacy PCI card then the X500 is the one to choose.

Typical configurations of the NotePAC are considerably more powerful than the X500 and include an Nvidia Quadro RTX4000 graphics card in one of the PCIe slots.

Announcing the NotePAC-III-PRO-V POWER PAC

4+ hour battery life rugged portable

The NotePAC-III-PRO-V is the most powerful computer in it’s class. Triple screen portable computers with 16 core Xeon’s and expansion slots are inherently both powerful and require external power…. Until now!

An additional machined aluminum chassis attaches to the NotePAC-III-PRO-V behind the main chassis, and out of view when using the system. Six x 81Wh batteries give a run-time of over four hours*, without replacement. Using an external charger, unlimited battery powered performance is possible. (With everything maxed out, 100% CPU utilization and Passmark system test maxing out the stress, the battery still lasts for 1.5H.)

Physically mating to the NotePAC-III-PRO-V to form a single transportable package means the system is still robust, reliable and ergonomic to use. The Power PAC chassis is less than 2.75” deep.

The external PSU is a 600W 100-240V AC-DC adaptor putting out 19V and 31.6A through a mil-spec power connector.

Weight: Battery chassis without batteries: 13.2lb, with six batteries: 19.8lb
Includes: USB cable, Power cable, DVD driver.

*Actual run-time may vary according to environmental conditions, workload, battery age etc.

Video capture hardware solution

Many security and surveillance missions rely on video. They need to monitor, capture, and disseminate video feeds. If a picture tells a thousand words, then a video is a library full of information. Capturing, processing, and evaluating video footage in a mobile environment can be challenging. Portexa now has a video capture laptop that makes deployed information gathering and video analysis a reality.

The NotePAC-III is a triple screen portable laptop. Machined from aluminum, and with high-end graphics and a video capture card designed for use in theatre. The NotePAC-III has passed Mil-Std 461 (EMC/EMI), DTE-901E (Shock/Torpedo Strike) and 810G (environmental).

“We are proud to have helped develop this excellent deployed solution.”

Multi-touch portable workstations

The latest touch screen technology is now available on large deployable workstation screens.  The ACME MegaPAC is now available with Projected Capacitive Touch screens.  Single, dual and triple screen workstations are available, and whichever system suits your needs, all screens support multi-touch input.

Almost everyone today is using touch-enabled mobile devices, tablet devices, or laptops on a daily basis. Multi-touch capabilities are merely table stakes now in mobile computing devices, and the gaming or signage industries.

Touch screens on mobile devices were revolutionized in 2007 when Apple released the first iPhone.  Of course, Apple did not invent the technology, but it was the first time it was made available on a mass-market device.  What made the iPhone tech interface different?  Gestures, pinch and reverse pinch- to zoom out and in, swiping, etc.  Before that, touch devices were restricted to single points (like clicks).

Now multi-touch gestures are available on the 24” displays of the MegaPAC portable workstation. 

If we take a look at the original touch-screen technologies we can trace the evolution and understand the technology behind multi-touch displays:


Some of the earliest touch displays used infra-red beams of light in a grid.  Sensors would ordinarily ‘see’ the beam, but when a finger was placed on the display, it broke one or more beams, giving the touch screen controller an X & Y coordinate for the ‘break’ and provide a ‘touch’ input.  This technology is still in use as it allows the display glass to be made really tough, unlike the restive and capacitive alternatives.

24" display portable touch screen workstation

IR Touch screens are suitable when a harsh environment (for example one that will be used by the public) is expected.  They are:


  • Vandal-proof, wear-resistant
  • Maintenance-free, longer life expectancy
  • Versatile touch object (Pointer or finger or glove)
  • Super transparency (no membranes between the display and user)
  • Operable in various light conditions, indoors and outdoors

These sorts of touch displays are usually found in POS, ATM, Kiosks, gaming machines, and industrial control systems.

Touch Screen Technologies

Resistive touch screenResistive touch screens

Resistive touch screens work by sensing the closing of a contact between two conductive membranes.  There are typically an array of dots, visible upon close inspection, that holds the two membranes apart until the ringer or pointer closes the gap by deforming the membrane.  This highlights one of the advantages of resistive screens over capacitive technologies – the pointing device does not need to be conductive, so a fingernail, a glove or a stylus can all work.  Resistive touch screens can be quite precise and don’t suffer from calibration drift as much as some capacitive screens.

Disadvantages are that there are at least two layers of membrane – typically plastic – between the display and the user, which reduces light output, and therefore reduces brightness.  Over time, the flexible membrane can become fatigued and ‘cloudy’ further reducing display clarity.  The other big disadvantage is that resistive touch screens can only detect a single pressure point – so there are no multi-touch gestures like pinch to zoom.

Surface acoustic wave touch screenSurface acoustic wave

Surface acoustic wave touch screens work by sending an ultrasonic wave (ultra-sound wave) across the surface of the glass.  Sensors detect the reflected wave and in some cases the attenuated wavefront that is caused by the pointer or finger.  This is then translated into an X-Y coordinate for the touchpoint.

Capacitive touch screenTraditional capacitive touch

Otherwise known as surface capacitive – work by detecting a change in capacitance of the field in front of the screen caused by a conductive entity of some sort.  Usually a finger.  Capacitive touch screens are commonly made of two layers – a surface insulator and a transparent conductive layer below it. As the human body is an electrical conductor when the touch panel is touched with a finger the electrostatic field of the panel is distorted.  The touch screen controller then decodes the changes in capacitance and returns a touchpoint to the system.  The advantages are that there is no membrane that needs to flex, so the touch-screen should last longer.  Disadvantages include possible drift over time on large displays, which require periodic re-calibration.  Because the sensor is a glass panel, there is less visual degradation than with resistive screens.

Projective Capacitive Touch Screen TechnologyProjective capacitive touch

Instead of one capacitive sensor, there are many, usually on two layers of transparent conductors.

Projected Capacitive Technology (PCT) is fast becoming one of the most prevalent touch technologies for touchscreens. PCT technology is what allows us to tap, pinch, zoom, and scroll with various gesture controls and using multiple fingers, and can be used in a wide range of applications from consumer devices to commercial products. 


PCT devices identify touch by measuring the capacitance at each addressable electrode in a dual-layer grid. When you touch the surface of a capacitive device, there is a disturbance in its electrical field (capacitance), which allows the device to determine when and where the touchpoint occurred.

PCT technology uses two main types of sensing methods, self-capacitance and mutual capacitance, each having its own advantages and disadvantages. In short, self-capacitance devices offer a higher signal strength and sensitivity to touch but does not support multi-touch (more than 2 touch-points) like mutual-capacitance devices.


“Projected capacitive technologies detect touch by measuring the capacitance at each addressable electrode. When a finger or a conductive stylus approaches an electrode, it disturbs the electromagnetic field and alters the capacitance. This change in capacitance can be measured by the electronics and then converted into X,Y locations that the system can use to detect touch” ( from 3M)


ACME’s addition of PCT technology to the MegaPAC results in a superior portable computing platform with a durable, UHD multi-touch touchscreen. The MegaPAC is a high performance, high-fidelity interactive solution that meets customers’ expanding user interface requirements.

Mil-DTE-901E Lightweight. The lightweight test is a test performed on the lightweight shock machine. The weight of the test item including fixture to attach it to the test machine shall be less than 550 pounds.

Items to be tested shall be classified in accordance with one of the following grades, as specified:

Grade A. Grade A items are items which are essential to the safety and continued combat capability of the ship.

Grade B. Grade B items are items whose operation is not essential to the safety and combat capability of the ship but which could become a hazard to personnel, to grade A items, or to the ship as a whole as a result of exposure to shock.

Environmental Testing – Shock

Rugged Mil-Spec triple-screen laptop with 16 cores

MIL-DTL-901E is the detailed specification of a suite of tests for high impact shock for machinery, equipment, systems, and structures aboard a ship or submarine.

As part of a suite of tests required for deployed Navy systems, the Portexa NetPAC-III has been tested to the new Mil-DTL-901E standard.

Mil-DTL-901E replaced MIL-S-901D in June 2017.

MIL-DTL-901E goes beyond MIL-S-901D by specifying detailed testing procedures, including diagrams and examples.

The tests were performed at an accredited third-party test house and resulted in a clean pass.  The Mil-DTL-901E Laptop test consists of:

  • NotePAC-III-PRO is classified as a lightweight, Grade B test
  • 9 Blows from 400lb hammer in 3 axis
  • Blows from 1ft, 3t, and 5ft
  • The unit was fully operational after the test

January 2020 UPDATE: Now shipping with 16 core processor!

“901-E is a pretty violent test – and is usually reagrded as destructive.  The NotePAC-III-PRO booted up just fine after the test was completed.”


“This specification covers high-impact (H.I.) shock testing requirements for machinery, equipment, systems, and structures aboard surface ships, including carriers unless otherwise noted, and submarines, herein referred to collectively as “ships”. The purpose of these requirements is to verify the ability of shipboard installations to withstand shock loadings due to the effects of nuclear or conventional weapons or environmental mechanical shock during operation.”


The NotePAC-III-PRO falls under the category of ‘Lightweight shock test’. Three blows at hammer heights of 1, 3, and 5 feet shall be applied parallel to each of three mutually perpendicular axes of the item being tested. This is accomplished by attaching the test item by fixtures to an anvil plate and striking the anvil plate by three mutually perpendicular blows. Grade B items. Grade B items shall withstand shock tests conducted in accordance with this specification without creating a hazard (see 6.6.16) to personnel operating or manning Grade A equipment, including personnel at battle stations, or to Grade A items. Unless otherwise specified (see 6.2.1), the following shock test acceptance criteria shall apply to Grade B items, including all criteria identified in the definition of hazard (see 6.6.16):

a. The shock tested item, portions thereof, or the contents thereof shall not come adrift due to exposure to shock. Exceptions to this criterion, which shall be approved by the Technical Authority on a case basis, will be acceptable in cases where it can be demonstrated that the weight, shape, and all other characteristics of the item that has come adrift are such as to preclude a significant impact threat to personnel or adjacent Grade A items.

b. Injurious, flammable, radioactive, acidic, caustic, or otherwise hazardous liquids, solids, or gases shall not be released as a result of exposure of the tested item to shock. Exceptions to this criterion, which shall be approved by the Technical Authority on a case basis, will be considered in cases where it can be demonstrated that the nature, location, rate, or total possible amount of leakage is such as to prevent development of a significant threat to Grade A systems, personnel, or to the ship as a whole. In addition, and for purposes of this criterion, any fluid whose operating temperature is above 150 degrees Fahrenheit (°F) or below 0 °F shall be considered hazardous. Fluids at any temperature shall be regarded as hazardous if they might cause an electrical short.

c. Tested items shall not demonstrate a potential for fire hazards. Any evidence of electrical shorts, the release of flame, smoke, or sparks shall be cause for rejection of the tested item, unless otherwise specifically approved by the Technical Authority on a case basis.

d. It is not required that Grade B items be operable after shock-testing.

Note: The NotePAC-III was fully operational after the test.

A very bright display can still be difficult to read outdoors because it is very difficult to compete with the Sun!  To improve usability, the MilPAC-III sunlight readable displays may be adjusted to a host of different opening positions, and the tilt of the whole unit changed using the robust foot.

Ultra-bright displays

Bright and uniform

The new displays’ contrast ratio exceeds 400:1 while providing deep blacks and extremely bright and readable detail. The 1000 cd/m^2 displays were tested for maximum brightness using a Topcon BM-9 luminance meter. Measured maximum white luminance was 1053 nits.

  1. MilPAC-III is in continuous use in-theatre.  The video feed from drones is fed to the CIC for analysis.
  2. Compressed video may then be sent to command for subsequent evaluation.
  3. Video feeds can be mirrored through HDMI ports on top of the unit to allow the operator to share engagement data with the commanding officer.
