Title: Floor underlayment
Inventor: JONES MATT
IPC: E04F15/18
Filed: 2005-09-01
Abstract: The invention is directed to a floor underlayment material comprising a film sheet having an inner surface attached to a foam sheet and an outer surface including a plurality of recesses formed therein.

Inventor: MOSEBROOK DONALD RAY
IPC: H05B37/02
Filed: 2004-04-30
Abstract: Systems and methods for providing a load control device, such as a DALI  ballast, having an infrared receiver. The load control device resides on a digital communications link and receives infrared commands via a lightpipe.  The commands are input to a microprocessor to set an address of the load control device. Addressing the load control device in this manner allows plural control devices residing on a single communications link to be addressed by the same short address. The control devices may be removed and replaced, and the short address and zone assignments of the removed devices may be reassigned to the replacement devices via infrared communication. The load control device may be placed into various modes (e.g., a programming mode or addressing mode) via commands received over the infrared receiver.

Title: Miniature pulsed fiber laser source
Inventor: VARSHNEYA DEEPAK
IPC: H01S5/12
Filed: 2004-06-14
Abstract: A pulsed fiber laser and associated electronics contained in a miniature package is disclosed. The Pulsed Fiber Laser Source (PFLS) can be a single-stage high gain master oscillator power amplifier (MOPA) type fiber laser source. The PFLS can include a distributed feedback (DFB) laser, a narrowband optical filter, a broad area high-power pump diode, and Erbium/Ytterbium (Er/Yb) double cladding doped fiber. Input electrical pulses drive the DFB  laser diode to emit optical pulses that are then amplified by the optical amplifier. Active and passive cooling elements may be incorporated for continuous operation without rest time. Passive cooling for intermittent pulsed applications allows the laser source to be miniaturized by eliminating active cooling elements and associated power supplies and controllers. Low duty cycle relaxes drive requirements and further reduces the size. The PFLS  can be used for long distance ranging, communication by retro-modulation, and communication in presence of atmospheric attenuation.

Inventor: BUTTERFIELD ROBERT D
IPC: A61M5/142
Filed: 2004-12-31
Abstract: A system for determining whether the pressure in a fluid line upstream of an infusion pump is becoming lower as pumping draws fluid from the fluid line and fluid container due to a lack of proper venting. An initial pressure is sensed by an upstream pressure sensor at the start of an infusion. After a period of time, which may be determined either by monitoring infusion time or the number of pump cycles completed, a second pressure is sampled and compared to the initial pressure. Various analytical methods may be applied to the sensed pressures to determine upstream pressures or trends. Where an upstream pressure reading indicates a lack of proper venting, an alert signal is provided. Continuous monitoring may occur in which succeeding samples are compared to preceding samples to determine upstream pressures or trends.
