Abstract

A hybrid power supply provides powers to a load, such as a light emitting diode (LED) backlight display, using pulse wave modulation (PWM) enable signal to control activation of a linear power supply and a switching power supply. During an initial part of an active portion of a duty cycle of the PWM enable signal, the linear power supply is activated to supply the load with constant current. During the remainder of the active portion of the duty cycle of the PWM enable signal, the linear power supply is deactivated and the switching power supply is activated to provide current to the load. A bias current and voltage may be provided to the LED during an inactive portion of the duty cycle of the PWM enable signal. The hybrid power supply combines the high efficiency of the switching power supply with smooth dimming control at low luminance of the linear power supply.

Method and apparatus for maximizing the usable bandwidth for High Performance 1553 terminals operating concurrently on the same physical bus with legacy 1 Mb/s MIL-STD-1553 terminals. More specifically, the method and apparatus provides implementation for predictive cancellation by synthesizing an estimate of the 1 Mb/s MIL-STD-1553 component of a composite 1 Mb/s plus High Performance 1553 input signal using either of two different techniques: (1) a combination of digital and analog techniques; and (2) an all digital technique. The synthesized signal is then subtracted from the composite signal. Both techniques employ an algorithm for minimizing the effects of clock skew between 1 Mb/s 1553 transmitting clocks and the local High Performance 1553 sampling clock. Both techniques also incorporate an adaptation algorithm for developing and maintaining digital models of 1 Mb/s 1553 signals received from multiple 1 Mb/s 1553 terminals on a bus.

Abstract

Solid state power controllers are described that include a switch controlled by a microcontroller and communication contacts. In one aspect of the invention, the microcontroller is galvanically isolated from the communication contacts using magnetoresistive isolation. In another aspect of the invention a number of solid state power controllers are connected to an external microcontroller to form a power distribution array. In addition, messages exchanged between the external microcontroller and the solid state power controllers can be used to configure the solid state power controllers and provide a user interface.

Abstract

A latch system including a first portion and a second portion which are attached to corresponding pieces. The first portion is engageable with the second portion. A drive device is coupled to at least one of the first portion and the second portion for controllable operation of the device to engage and disengage the first portion and second portion. A controller is provided and coupled to the drive device for controllably operating the drive device to engage and disengage the latch. The first and second portion may be provided in the form of a hook and keeper configuration with one of the hook portion and keeper portion being driven by the drive device. A sensor may be provided on the latch assembly coupled to the controller for detecting at least one condition such as the latch being engaged or the latch being disengaged. Also disclosed is a method of latching using a first portion, second portion, drive device and controller for controllably latching and unlatching a latch assembly.

Abstract

A clamp for securing an element to a structure comprises, a first part and a second part, engageable into a assembled state about the element to be secured. A flexible element is attached to the first part and the second part, which flexible element allows independent movement of the first part and second part when the clamp is not assembled. The clamp further comprises a tensioning mechanism adapted to hold the flexible element taught when the clamp is in the assembled state.

Abstract

Pyrotechnic systems and associated methods are disclosed. In one embodiment, a pyrotechnic system includes a combustible material in a housing having a first and second portion. The first portion of the housing can have an inlet for receiving combustion products and the second portion can have an outlet to propagate combustion between the second portion of the housing and the combustible material. The system can further include a combustible carrier material movable from the first portion of the housing to the second portion of the housing. The combustible carrier material can be ignited in a first portion of the housing and capable of sustaining combustion while being moved to the second portion of the housing. Additional embodiments can include a seal positioned to block a migration of combustion products between the first and second portions of the housing when the combustible carrier material is in the first portion of the housing. Still further embodiments can include a vent system located proximate to the first portion of the housing and the inlet wherein the vent system includes a passageway to allow combustion products to migrate away from the first portion of the housing and/or the inlet. In yet a further embodiment, the system can include at least one gasket positioned proximate to the outlet to prevent the migration of combustion products to the combustible material except from the outlet.
