Abstract: A one-piece framework for holding the filter media of an air filter includes a pair of end walls integrally connected to a pair of frame members by a living hinge so that they may be pivotally moved between an assembled position and an unassembled position. A pair of sidewalls are integrally connected to the frame members by a living hinge only at their outermost ends so that they, too, may be pivotally moved between their assembled and unassembled position. Each of either of the sidewalls or end walls is provided with a tab-type latch which includes a button undercut at least a peripheral portion thereof. Each of the other sidewalls or end walls has an opening formed therethrough. The opening is defined by a wall shaped in accordance with and frictionally surrounding the undercut button in a snap-fit to hold the sidewalls to the end walls in an assembled state.

Abstract: A broadband customer premises equipment ("CPE") interface device (100) interfaces with conventional telephones (152), screen phones (154), and broadband data and video devices. The interface device includes circuitry to connect with a telephone network (102) via a first telephone connection (104) and circuitry to connect with a broadband network (106) via a second, broadband connection (108). In addition, the interface device (100) includes ADSI off-hook alerting ("AOHA") circuitry and adds ADSI script management server ("ASMS") circuitry to provide noninvasive programming of screen phonetype CPE devices (154). ASMS programming information for a CPE device is transferred to the interface device (100) via the broadband network (106) and stored in the interface device. The AOHA and ASMS circuitry requests the CPE device (154) to go off-hook when idle, without ringing the CPE device (154) like a conventional telephone call. When the CPE (154) is idle, the AOHA and ASMS circuitry routes the programming information from storage (142) into the CPE (154).

Title: Gas turbine combined cycle
Inventor: UEMATSU KAZUO
IPC: F02C7/143
Filed: 1999-02-25
Granted: 2004-05-11
Abstract: The invention provides a gas turbine combined cycle structured such that an intermediate cooling device for cooling a compression air discharged from a low pressure compressor, so as to reduce a load of a high pressure compressor, is provided. The gas turbine combined cycle in accordance with the invention is structured such as to branch water from a condenser to a steam generating device for generating steam. Exhaust gas discharged from a steam turbine is condensed to water. Compression air discharged from a law pressure compressor is cooled by being supplied to an intermediate cooling device, and is then supplied to a high pressure compressor. Steam which heats and operates the steam turbine is generated by the heat recovered by the cooling of the compression air in the intermediate cooling device. Accordingly, there can be obtained a gas turbine combined cycle having the advantage of the conventional intermediate cooling type gas turbine combined cycle, but exhibiting an improved combined efficiency.
Patent CA-2264443-C (CA)
Title: Switching power supply
Inventor: WATANABE HARUO
IPC: H02J7/00
Filed: 1999-03-05
Granted: 2006-02-14
Abstract: A switching power supply has first and second switching elements that are alternately turned on to cause an alternating current to flow through a primary winding of a transformer. The alternating current flowing through the primary winding induces voltages respectively across first and second secondary windings of the transformer. Synchronous rectifying transistors are turned on by the voltages induced across the first and second secondary windings, causing a current to flow alternately through the first and second secondary windings. Either one of the first and second switching elements is turned on while the other is being turned off, except for short off-times in which both the first and second switching elements are prevented from being turned on. As a result, when currents flow through the first and second secondary windings, the synchronous rectifying transistors are turned on. Therefore, no current flows through internal parasitic diodes of the synchronous rectifying transistors, and hence any loss caused thereby is very small.

IPC: G06F9/445
Filed: 1999-06-29
Granted: 2003-10-14
Abstract: A method and system are disclosed for configuring PnP devices for a computer operating system by initiating a power on self test (POST) within a computer system for configuring PnP and PCI devices. During the process of configuring PnP and PCI devices, a list is composed of devices that are not absolutely necessary for booting the system (e.g. modem or ethernet controller). While the PCI devices are configured, if the system has no usable IRQ's, POST takes one from a nonessential PnP ISA (Industry Standard Architecture) device in the list, and gives it to the PCI device. The POST operation searches for the presence of a PnP operating system option while progressing through the startup sequence (of bootable media), and activates or deactivates all devices, depending on the type of media being attempted. If the medium is the hard disk (where the PnP operating system option resides), all of the PnP devices in the list are deactivated. If the medium is any other type (where a PnP operating system option is not likely to reside) the devices are activated.
