Abstract: Devices, systems and methods implement a synchronized, multi-channel wireless network having a low-power, wireless wide-area network (LPWAN) architecture that makes narrowband radio frequency channels useful for Machine-to-Machine (M2M) and Internet of Things (IoT) applications, and is scalable. A control stack controls delivery of API client datagrams to nodes via base transceivers using forward channels and nodes respond using reverse channels. Forward and reverse channels are synchronized and grouped into sectors or areas of coverage. Forward channel framing structures and node processes allow nodes to remain in inactive, low power state for long periods of time, and consider large numbers of possible RF channels in a time-efficient and energy-efficient manner.

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: An apparatus and methods for analyzing feet which utilize 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 smoothes 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.
