Abstract: A digital compensation system for a radio frequency (RF) power amplifier module is disclosed. The digital compensation system includes an RF power amplifier having a first input, a first output, and a first bias input, wherein the RF power amplifier is configured to receive an RF signal at the first input and generate an amplified version of the RF signal at the first output. The digital compensation system also includes compensation circuitry coupled between the first input and the first output and a bias output coupled to the RF power amplifier, wherein the compensation circuitry is configured, in response to the RF signal, to generate or adjust a bias signal at the first bias input to correct dynamic bias errors caused by amplification variations that have time constants.

Abstract: Systems and methods described herein provide for a circuit board having multiple fault containment regions therein. The circuit board includes a first fault containment region defined, at least in part, by first and second metal layers coupled to ground. The first fault containment region includes a first signal layer between the first and second metal layers, a third metal layer between the first and second metal layers, the third metal layer connected to the first signal layer to provide a return path for the first signal layer, and a fourth metal layer between the first and second metal layers, the fourth metal layer connected to the first signal layer to provide power to the first signal layer. The circuit board also includes a second fault containment region in a plurality of layers below the first fault containment region.

Abstract: One embodiment of the present invention comprises a collapsible, manually-extracted paper-towel-roll storage and dispensing container. Paper towel rolls are manually loaded horizontally in one or more vertical stacks inside the storage and dispensing container. A dispensing aperture is included at the bottom of the front face for manual removal of the paper-towel rolls from within the container. A viewing aperture is also contained on the front face of the container for viewing the contents of the storage and dispensing container. A removable door-mounting bracket attaches to the back side of the storage container and dispenser for hanging the container from the top of a door. Either the top or bottom face of the container may be opened for loading and both faces may be opened for folding the container flat for efficient storage when not in use.

Abstract: This invention involves a wearable computer having computer components movably located in a collar that the user wears around his or her neck. The computer components can be a display or monitor, or a microphone or any other computer component.

Abstract: The present invention is an improvement on the functionality of garments of personal protection. The design is a portable computer system with all of the system components incorporated into an item of personal wear, for example into a garment such as a vest, that is shielded by a layer of armor. The armored garment will protect the user and completely house the processing unit, input device, and any peripheral attached to the processing unit.

Abstract: A lamp assembly is provided which includes a lamp/reflector subassembly coupled together by a lamp coupler. The lamp coupler may include two coupler segments which are configured and dimensioned such that the lamp/reflector subassembly may be enclosed within the two coupler segments which may then be latched together. When latched together, the light source of the lamp will be properly positioned relative to the reflector to provide the desired lumen output. Such lamp assembly does not require a costly lamp to reflector focusing operation. A lamp coupler useful in such lamp assembly is also provided.

Abstract: An aqueous antimicrobial liquid cleaning formulation comprising about 0.2 to 4 parts of a cationic quaternary ammonium compound; about 2 to 10 parts of one or more nonionic surfactants; and about 1 to 10 parts of a polyfunctional alcohol wherein the weight ratio of nonionic surfactant and polyol to cationic surfactant is at least about 4:1 to about 28:1.
