Wireless access point simultaneously supporting basic service sets on multiple channels

The present invention provides a technique for an access point (AP) to maintain a basic service set (BSS) on two or more channels simultaneously by temporarily blocking one BSS and servicing the other BSS while the other BSS is blocked, thereby providing an efficient way to create a dual cell AP with only a single radio. In an embodiment of the invention, a method for servicing a first set of wireless stations operating on a first channel of an access point and a second set of wireless stations operating on a second channel of the access point comprises transmitting, at a first time, a first frame from the access point to the first set of wireless stations via the first channel, the first frame having duration data directing the first set of wireless stations to cease transmitting until a second time represented by the duration data and servicing the second set of wireless stations via the second channel of the access point for at least a part of a time period between the first time and the second time. The method further comprises transmitting, at the second time, a second frame from the access point to the second set of wireless stations via the second channel, the second frame having duration data directing the second set of wireless stations to cease transmitting until a third time represented by the duration data of the second frame and servicing the first set of wireless stations via the first channel of the access point for at least a part of a time period between the second time and the third time. The method also may comprise transmitting a Delivery Transmission Indication Map (DTIM) frame prior to transmitting each of the first and second frames. The transmission of the DTIM frame preferably occurs substantially simultaneously with a Target Beacon Transmission Time (TBTT) of the access point.

Cattle management method and system

A highly automated method and system for providing individual animal electronic identification, measurement and value based management of cattle in a large cattle feedlot. Through the use of (1) a computer system integrated with (2) automatic individual animal identification (3) multiple measurement and remeasurement systems with automatic data input and (4) a cattle handling and sorting system, animals are individually (a) identified and (b) measured by weight, external dimensions and characteristics of internal body tissue. With this information together with animal physiological characteristics and historical data, the computer system calculates the optimum (c) slaughter weight, (d) economic end point and (e) marketing date for shipment to a packing plant. After measurement, individual animals are (f) sorted by direction of the computer in response to calculations from the measurements. The computer system also calculates from individual animal data and other data (g) each animal's pro rata share of total feed intake for the animal's feed group. The computer system (h) stores individual animal measurement, performance and location data, which is used by management to (i) select animals for shipment from the feedlot for slaughter at the optimum time. Following an animal's shipment to a slaughter facility, its identification in the computer system is used to (j) correlate the live animal physical characteristics and performance data to the measured and evaluated carcass characteristics data obtained during the slaughter process and (k) build a data base to more accurately identify and measure value-based characteristics in subsequent animals produced and fed for more effective value-based selection and management of those animals.
