Title: System and method for determining a handoff target base station in a mobile communication system
Inventor: JUNG KEE SUNG
IPC: H04B7/26
Filed: 1999-05-08
Granted: 2004-10-12
Abstract: A mobile communication system performs handoff taking into consideration a travelling direction of a mobile station. A mobile station measures strengths of pilot signals from base stations adjacent thereto and transmits information about the measured strengths to a BSC. The BSC then selects one of the base stations as a handoff target base station depending on the measured strength information and location information of the mobile station and the base stations. The weights are applied to the adjacent base stations according to directions of the adjacent base stations based on a travelling direction of the mobile station, which is predicted according to movement of the mobile station.

Abstract: In a wireless communication system, the constellation mapping scheme employed may be changed on a per-time-slot basis, i.e., from time slot to time slot, so that the constellation used to encode the symbols of each time slot may be different for each time slot within a single frame and may be different for a particular time slot in different consecutive frames. In other words, several constellation mapping schemes are available, with each providing the ability to transmit a different number of bits per symbol, and the particular constellation mapping scheme employed for any time slot need be selected for that time slot only. The ability to use any particular constellation mapping scheme is dependent on the current channel quality. The particular constellation mapping used for the user data of the time slot may be indicated in the preamble of the time slot. To this end, each time slot may have its own preamble that is mapped with a constellation mapping scheme which is a) known a priori, b) may be the same for all time slots, and c) may be different from the constellation mapping scheme used to encode user data in the time slot. A receiver can determine the constellation mapping used for each time slot from solely from the preamble of the time slot.

Title: Packet classification engine
Inventor: HEBB ANDREW T
IPC: H04M3/00
Filed: 2000-11-28
Granted: 2007-01-09
Abstract: Packet classification apparatus includes a rule memory and a criterion memory. One type of rule memory entry contains an operator and a pointer to a criterion memory entry. The operator defines a comparison operation to be performed, such as EQUAL (exact match) or LESS THAN. The criterion memory entry contains one or more values to be used as comparands on one side of the comparison, where corresponding values from a received packet appear on the other side of the comparison. Control logic responds to packet classification requests to retrieve a rule memory entry from the rule memory, retrieve the criterion memory entry identified by the criterion memory pointer in the rule memory entry, and perform the operation specified by the operator in the rule memory entry on the values in the criterion memory entry and corresponding values included in the classification request. This procedure is repeated for a sequence of rule memory entries until an ending condition is encountered, whereupon a packet classification result is generated reflecting the result of the classification operations. This result is provided to a packet processor to take the appropriate action based on the classification result.

Title: No-spill drinking cup apparatus
Inventor: HAKIM NOURI E
IPC: B65D8/16
Filed: 1999-08-20
Granted: 2008-05-20
Abstract: A no-spill cup (22) and valve assembly (31) which provides an seal against accidental liquid flow. The suck-ing action at the cup spout creates nega-tive pressure against a valve member (37, 39) near the spout (14) having an opening therein, causing the valve member (37, 39) and opening to move off of a pro-truding member, thereby unblocking the opening in the valve. When the open-ing is unblocked, liquid can flow freely through the valve and spout. When not in use, the valve sits in a closed position, with the opening in the valve sitting on a protruding member and pressed against the protruding member's base, sealing off the opening in the valve assembly (31). The closed position provides a seal against fluid leakage during inadvertent spills. The cup assembly allows variable liquid flow rates by rotating the position of the valve assembly in the cover (11) of the cup.

Inventor: BOWMAN WALTER WILLIAM
IPC: F24F11/76

Granted: 2005-08-16
Abstract: A fan motor speed control system for controlling the fan motor speed of an air conditioning system includes a power output circuit including a power triac which is turned on and off by an opto-isolator connected to a pulse generator circuit for varying an AC voltage waveform imposed on the fan motor. The pulse generator circuit is connected to heating and cooling ramp circuits and a minimum speed circuit to provide a variable voltage signal imposed on the pulse generator circuit corresponding to the temperature difference sensed by a return air sensor and a heating or cooling sensor or by separate heating and cooling sensors disposed adjacent respective heating and cooling heat exchangers of the air conditioning system. An adjustable minimum speed circuit and a cutoff circuit are provided to control motor minimum speed or motor shutoff when a predetermined minimum speed is reached to prevent motor bearing failure or overheating. Sensor protection circuits in the control system operate to drive the motor to full speed if any of the temperature sensors experience an open or short circuit condition. The control system circuit maximizes air conditioning system efficiency by capturing additional heating or  cooling effect, reduces noise associated with motor startup and shutdown, and reduces rapid change in the sensed temperature in the air conditioned space during motor startup and shutdown.
