Abstract: Systems for holding tactical gear, such as firearm magazines, weapons, etc., and for connecting such holders to a harness are described and may include a carrier, and an accessory holder that is configured to attach to the carrier. The carrier and/or the accessory holder may be formed from substantially rigid materials, such as plastic or the like, and may be configured to be easily attached and detached from one another, using preconfigured, integral connectors. The connectors may be configured to resist rotation of the carrier and accessory holder with respect to each other, and/or to secure the accessory holder at a fixed angle with respect to the carrier. The accessory holder may also include flanges, surface treatments, or other features, that assist in holding the accessory in the holder.

Abstract: A wearable load redistribution system can include a base support structure and a thoracic frame configured to surround an upper torso of a wearer of the system. The base support structure can include a support frame and a plurality of support members disposed at distal ends of the support frame. The thoracic frame can include a coupling structure, a front plate, and a plurality of struts. A connector member can removably connect the coupling structure to the support frame. The plurality of struts is mated to the front plate to redistribute a weight of the front plate away from shoulders of the wearer and towards the base support structure.

Abstract: A lighting device including one or more emitters configured to emit a first spectrum and a second spectrum; a switching mechanism with at least two switching elements configured to change an emitted light from a first spectrum to a second spectrum, and to change a blink pattern of emitted light; a feedback mechanism configured to provide tactile feedback when the illumination device is activated or deactivated, or when a mode of operation is changed; a translucent unitary housing extending substantially upward and inward from a base of the device; and a power source received in the housing. The first spectrum may be a non-visible light spectrum and the second spectrum may be visible light spectrum.

Abstract: A mass airflow measuring system includes an air conduit and a sensor assembly mounted to the air conduit, including a unitary one-piece first section which in cross section defines a first channel, a second channel and a wall separating the two channels. A second section has similar components. A unitary one-piece corner section, in cross section includes four legs, each defining a respective channel. A respective leg is mounted in a respective one of the channels of the first and second sections to communicate the sections with each other through the channels defined in the corner section legs. A sensor housing is mounted to one of the sections and includes an inlet opening communicating with the first channel and an exit opening communicating with the second channel. A mass airflow sensor communicates with a sample channel defined in the housing.

Abstract: Embodiments include a method and apparatus for an integrated illumination device mount and for mounting the integrated illumination device and mount to a firearm or helmet. In some embodiments, the integrated illumination device mount is a low profile mount. In some embodiments, the integrated illumination device mount allows rigid mounting of an illumination device to a rail of a firearm. In other embodiments, the integrated illumination device allows pivotal mounting of the illumination device to a rail of a firearm. In yet other embodiments, the integrated illumination device mount allows pivotal mounting of the illumination device to a rail of a helmet.

Abstract: An adjustable firearm handguard mounting system configured to facilitate setting the rotation of the handguard relative to a barrel nut and then clamping the handguard to the barrel nut using non-parallel screws.

Abstract: Embodiments include a method and apparatus for mounting wearable ballistic body armor plates and accessories to a user. Embodiments may include a plate frame assembly comprising one or more plate frames and one or more ballistic body armor plates. The one or more plate frames may at least partially house the one or more ballistic body armor plates and hold them in position with respect to the one or more plate frames. A method of embodiments may include providing one or more plate frames and one or more ballistic body armor plates and using the one or more plate frames to hold the one or more ballistic armor plates in a fixed position with respect to the body armor plates. In some embodiments, the plate frame assembly is resistant to the absorption and/or accumulation of liquids and chemicals.

Abstract: A system, method and device for mass airflow sensor signal processing includes a microcontroller, a mass airflow sensor and an engine PCM. An analog-to-digital converter (ADC) converts a first output signal from the mass airflow sensor to a first VDC value. A digital-to-analog converter (DAC) converts a second VDC value to a second output signal associated with the mass airflow sensor. Transfer functions are obtained from a flow bench using the mass airflow sensor, performance air intake components, and stock air intake components. The microcontroller determines, from the first VDC value, a corresponding actual flow rate. From the actual flow rate, a corresponding stock VDC value is determined. The stock VDC value is then output to the DAC for conversion to the output second signal associated with the mass airflow sensor for communication to the engine PCM.

Abstract: An integrated spring bottom metal latch is disclosed that obviates the problem of rifles having heavy recoil from erroneously and unintentionally opening and dropping shells or magazines upon firing. The integrated spring allows for exact manufacturing versus compression springs. As a result, the presently disclosed invention may be utilized to address specific recoil requirements as found in any number of rifles exhibiting different recoil.

Abstract: A temperature control system, a wafer chuck, a thermal module for use with the chuck, and an apparatus for use in semiconductor manufacture are disclosed herein. The temperature control system includes: a target having a temperature, a fluid circulation loop coupled to the target for controlling the temperature of the target, a heating heat exchanger coupled to the fluid circulation loop for selectively providing heat to the fluid circulation loop, a cooling heat exchanger coupled to the fluid circulation loop for selectively providing cooling to the fluid circulation loop and a plurality of thermal electric elements carried by the target for selectively providing heating or cooling to the target. The heating heat exchanger and cooling heat exchanger provide gross control of the temperature of the target, and the plurality of thermal electric elements provide fine control of the temperature of the target.
