Abstract: Systems and methods are provided for reliable, wireless group messaging or alerting in a system having a database, switch, wireless network, and a plurality of intelligent mobile receivers. A message is broadcast to and received by a selected group of the mobile receivers. The network replies to the sender with detailed information about the individual members in the group. Each of the mobile receivers in the group can acknowledge the group message back to the system such as when the message is received, when the message is read, and a response when sent. The system employs centralized management to provide the sender with response information of the mobile receivers.

Abstract: Systems and methods are provided for reliable, wireless group alerting in a system having a database, switch, wireless network, and a plurality of intelligent mobile receivers, and preferably employing a modified two-way paging based on ReFLEX™ protocol information service (IS) messages and a novel ALOHA command for multicast acknowledgement from mobile receivers. An encrypted message is broadcast to and received by a selected number of the mobile receivers. The network replies to the sender with detailed information about the individual members in the alert group. Each of the mobile receivers in the group then acknowledges the common message back to the system, decrypts the message, displays it to the user, and allows the user to respond. The system employs centralized management to simplify the roles of the mobile users and administrators, minimizing configuration and operational human errors that would otherwise result in confusion or lost messages.

Abstract: A method and apparatus for measuring feet for fitting shoes which utilizes matrixes of pressures sensors and optical sensors connected to a controller and a monitor. An apparatus of the invention includes a housing which houses a controller and a monitor and defines left and right foot wells for receiving left and right feet, respectively. The floor of each foot well includes a pressure pad assembly which includes a matrix of pressure sensor contacts covered by a variably resistive pressure pad to form pressure sensor matrixes. A digital signal processor normalizes and smooths the pressure data for display on the monitor. Infrared LED's and phototransistors are located around the perimeter of each foot well and are utilized to measure the length, width, and heights of a foot. A microprocessor addresses each LED and phototransistor separately. The controller reads data created by the DSP and IR microprocessor, calculates additional data, and displays the resulting data on the monitor.

Abstract: An advanced telecommunication system is provided for central control of electronic signs. A display development kit is provided to create binary display programs which create visual activity on one or more electronic signs. These display programs are stored on the disk drive of a system control computer which periodically runs a system control program to upload display programs to the electronic signs using radiopaging signals. The system control program employs a telephone modem to connect through a public switched telephone network (PSTN) to a paging terminal. In accordance with the system control program, the system control computer divides each display program into multiple packets which are transmitted to the paging terminal as alphanumeric radiopages. The paging terminal encodes the packets into radiopaging format, frequency shift key modulates the data, and transmits the pages on a radio frequency channel. Electronic signs decode the radiopages into data packets.
