Methods and apparatus for limiting communication capabilities in mobile communication devices

Pub Date: 2005-05-12

Pub Number: US20050101287

Methods and apparatus for limiting communication capabilities in mobile communication devices are disclosed. In one illustrative example, a predetermined condition such as an unsatisfactory temperature or a low battery voltage is detected at the mobile communication device. At this time, a communication request for communicating information through a wireless communication network is received through a user interface. If the communication request is for a non-emergency communication, the non-emergency communication is inhibited during the existence of the predetermined condition. If the communication request is for an emergency communication, however, the emergency communication is allowed despite the existence of the predetermined condition. The emergency communication may be allowed at a reduced transmit power and/or using limited coding/modulation methods. The emergency communication may be a 911 voice call or an emergency message. The reception of communications may still be allowed but inhibited upon more adverse conditions.

Split radix multiplication

Pub Date: 2005-05-12

Pub Number: US20050102344

A first number is multiplied by a second number, by representing the first number as a first set of one or more W-bit wide numbers, and representing the second number as a second set of one or more W-bit wide numbers. Each of the W-bit wide numbers from the first set is paired with each of the W-bit wide numbers from the second set. For each pair of W-bit wide numbers, a set of sub-partial products is generated. Combinations of the sub-partial products are formed such that each combination is representable by a W-bit wide lower partial product and a carry out term that has fewer than W bits. The W-bit wide lower partial products and the carry out terms are combined to form the product of the first number and the second number. The carry out term is advantageously representable by (W/2)+1 bits.

Chair for healthy sitting

Pub Date: 2005-05-12

Pub Number: US20050099053

Disclosed is a supportive chair for sitting comfortably at low heights above and relative to the ground. Preferably, the chair comprises a primary seating surface and a secondary seating surface curving around the rear of the primary seating surface to provide additional support for the user. It is preferred that the secondary seating surface be inwardly and downwardly sloped and provide a low lateral boundary for the user, thereby promoting proper alignment of the buttocks on the primary seating surface. Thus, the chair raises the buttocks and hips of the user off of the seating level, creating a relative height difference between the hips and legs. This raising of the hips relative to the legs creates a sitting posture that promotes vertical back alignment. As a result, the user is able to comfortably maintain this position with a reduced amount of back muscle strain, allowing prolonged comfortable seating periods.

System and method for warm air space heating with electrical power generation

Pub Date: 2005-05-12

Pub Number: US20050098643

This invention provides a system and method for cogeneration of building heat and electric power and that efficiently interfaces a warm air heating system with a liquid-cooled electric power generator. The system and method utilizes an electric generator that is rated at near the time-averaged electric power consumption for the building. This generator is operated as the priority source of heat for the building, but normally only when there is a demand for heat in building. In this manner, the generator can run to generate a significant part of the building's electric power but in a manner that is typically supplemented in variable quantities by power from a public power grid. The heat output is directed via a liquid coolant circuit on the generator, as needed, to the warm air heating unit for the building. The warm air heating unit blows return air through a cabinet and out to the supply duct(s). The warm liquid coolant is directed through a primary heat exchanger in the cabinet. The air is passed over this primary heat exchanger to provide heat to the building. When heat from primary heat exchanger is insufficient to heat the building fully, an auxiliary heater, operated typically by burning fuel, supplements the heat through one or more auxiliary heat exchangers arranged in line along the airflow path with the primary heat exchanger. The blower that directs the airflow is controlled variably in speed to create the most efficient use of electric power by the blower and a desirable heated air delivery temperature.

Modularized electronic device operating status display architecture

Pub Date: 2005-05-12

Pub Number: US20050100287

A modularized electronic device operating status display architecture is proposed, which is designed for use with a modularized electronic device mounted on the inside of a chassis of an electronic system, and which is capable of detecting whether the modularized electronic device operates normally during operation to thereby display its operating status as light signals on the outside of the chassis to allow assembly personnel or user to learn the operating status by visually checking the externally-displayed light signals. The proposed modularized electronic device operating status display architecture is more advantageous to use in that it allows the assembly to be less complex in structure and more increased in productivity. Furthermore, it allows no removal and reconnection of electrical wires during the replacement of a faulted modularized device. This feature allows both assembly and maintenance of the modularized fan unit to be more convenient and efficient than prior art.

Pub Date: 2005-05-12

Pub Number: US20050100082

A method of reducing multiple access interference in a CDMA radio system uses a plurality of rake fingers to pre-process received signals but without demodulation or de-spreading. The outputs of the rake fingers are combined, normalised and then processed by an adaptive equaliser to recover orthogonality lost in transmission. The equaliser output is then subject to de-spreading and de-scrambling to recover the desired user signals. The equaliser is preferably adaptive order, the length being adapted in dependence upon the instantaneous signal to noise ratio.
