US Patent:

6484316, Nov 19, 2002

Filed:

Oct 14, 1998

Appl. No.:

09/172482

Inventors:

Conrad Lindberg - San Diego CA

Assignee:

ADcom Information Services, Inc. - Deerfield Beach FL

International Classification:

H04N 900

US Classification:

725 17, 725 18, 348 94, 455 2

Abstract:

A signal strength meter for use in determining an optimal position of a magnetic pick-up device. The signal strength meter includes a vertical synchronization processing circuit, and audio processing circuit and a power and control circuit. The signal strength meter receives vertical synchronization and audio signals radiated from a television set, as well as an audio test signal directly provided by a pattern generator. The signal strength meter determines parameters such as a phase stability of the vertical synchronization signal detected by the pick-up device, a level of the audio signal detected by the pick-up device, an audio phase measurement of the audio signal sensed by the pick-up device with respect to an audio test signal input directly to the signal strength meter, and an audio noise floor measurement.

Appl. No.:

7/087894

International Classification:

H02J 700

US Classification:

363 41

Abstract:

A method and apparatus for providing uninterrupted DC and AC power for a desktop personal computer is described. The source of the uninterrrupted DC and AC power is derived from an integrated power supply that is sized to fit within the existing housings of most desktop personal computers as a plug-in replacement for existing power supplies. A high degree of efficiency is obtained using an integrated design with the main power conversion derived from a DC/DC dual primary resonant converter. The main primary of the resonant converter is driven from a high voltage DC bus which is supplied from AC mains when available. When the AC mains is unavailable, the second primary of the DC/DC dual primary resonant converter receives power from a low voltage battery source. Secondaries of the converter produce low voltage DC for driving the personal computer, high voltage DC for augmenting the high voltage DC bus, which in turn is used to drive a DC/AC inverter for supplying uninterrupted AC voltage for powering peripherals such as a monitor, printer, etc. A medium-voltage secondary is also sourced from the converter which drives a battery charger to recharge an internal battery pafck upon restoration of the AC mains.

Appl. No.:

14/828334

Inventors:

Conrad P Lindberg - Fallbrook CA, US

International Classification:

F24F 11/00
G05B 15/02
F24F 11/02

Abstract:

A method of controlling a heating, ventilating, and air conditioning system on a customized schedule utilizes a master controller and a plurality of satellite vents. Each of the plurality of satellite vents is associated with a vent address which can be addressed through the master controller. A plurality of actuation commands, wherein each of the actuation commands contains a vent position which is transmitted to a specific vent of the plurality of satellite vents. The master controller utilizes a wireless transmitter to broadcast the actuation commands. Next, each of the plurality of satellite vents periodically listen for the actuation commands. A specific command of the actuation commands is executed if the vent address of the actuation command matches the physical address of the specific vent and a current time matches a set time of the specific command.

Abstract:

A disposable cassette for detecting nucleic acids or performing other assays. The cassette can be inserted into a base station during use. The cassette has numerous features to ensure correct operation of the device under gravity, such as vent pockets for enabling the flow of sample fluid from one chamber to the next when the vent pocket is unsealed. The vent pockets have protrusions to help prevent accidental resealing. The cassette also can have a gasket to ensure free air movement between open vent pockets. A flexible circuit with patterned metallic electrical components disposed on a heat stable material can be in direct contact with fluid in the chambers and has resistive heating elements aligned with the vent pockets and the chambers. The detection chamber, which houses a lateral flow detection strip can have a space below the strip that has sufficient capacity to accommodate an entire volume of the sample fluid entering the detection chamber at a height that enables the fluid to flow up the detection strip by capillary action without flooding or otherwise bypassing regions of the detection strip. The space can also contain detection particles. Recesses in in the cassette channels or chambers can have structures such as ridges or grooves to direct fluid flow to enhance rehydration of lyophilized reagents disposed in the recess. Flow diverters in the chambers can reduce the flow velocity of the sample fluid and increase the effective fluid flow path length, enabling more accurate control of fluid flow in the cassette.
