Method and system for wireless group communications
First Claim
1. A method for wireless communication between a controller and a group of user devices, each user device having a respective identification number (RFID), comprising:
- assigning a sequence number (PID) to each user device;
transmitting the PID from the controller to each user device; and
, in response to a message broadcast from the controller to the group of user devices, receiving a response from each user device in sequence, wherein each response includes the respective PID of the user device, and wherein each user device determines when to transmit its response by comparing its PID with the PID of each transmitted response.

Abstract
A method for wireless communication between a controller and a group of user devices, each user device having a respective identification number (RFID), comprising: assigning a sequence number (PID) to each user device; transmitting the PID from the controller to each user device; and, in response to a message broadcast from the controller to the group of user devices, receiving a response from each user device in sequence, wherein each response includes the respective PID of the user device, and wherein each user device determines when to transmit its response by comparing its PID with the PID of each transmitted response. The method supports group identification, middle stream devices, multifunction user devices (e.g., remote control, wireless mouse, motion detector), and remote programming of user devices and middle stream devices. Also, a matching method is provided for comparing a sample item to a reference item using the controller and user devices.

33. A system for wireless communication with a group of user devices, each user device having a respective identification number (RFID), comprising:
-
a processor coupled to memory and to a wireless network interface and adapted for;
assigning a sequence number (PID) to each user device;
transmitting the PID from the system to each user device; and
,in response to a message broadcast from the system to the group of user devices, receiving a response from each user device in sequence, wherein each response includes the respective PID of the user device, and wherein each user device determines when to transmit its response by comparing its PID with the PID of each transmitted response.

34. A computer program product having a computer readable medium tangibly embodying computer executable code for directing a controller to communicate wirelessly with a group of user devices, each user device having a respective identification number (RFID), the computer program product comprising:
-
code for assigning a sequence number (PID) to each user device;
code for transmitting the PID from the controller to each user device; and
,code for, in response to a message broadcast from the controller to the group of user devices, receiving a response from each user device in sequence, wherein each response includes the respective PID of the user device, and wherein each user device determines when to transmit its response by comparing its PID with the PID of each transmitted response.

35. A method for comparing a sample item to a reference item comprising:
-
selecting parameters for comparing the sample and reference items, the reference item having a predetermined rank score for each of the parameters;
selecting a distribution for tabulating votes received for each of the parameters for the sample item;
displaying the sample item, reference item, and parameters on a display screen, the display screen coupled to a controller in wireless communication with a group of user devices, each user device having a plurality of selection buttons for generating the votes for each of the parameters for the sample item;
receiving the votes at the controller and determining a rank score for each of the parameters for the sample item in accordance with the distribution; and
,displaying at least one indication of whether the rank scores for the sample and reference items match.
