Abstract: Systems and methods for providing biofeedback information to a subject for gait assistive therapy are provided. The system comprises an insole pressure sensor and means for communicating the pressure exerted by the subject on the insole pressure sensor to the subject. The insole pressure sensor comprises conductive elements in communication with a transmitter, which transmits a pressure signal to a receiver worn by the subject. The method comprises monitoring pressure applied by the subject to the insole pressure sensor, monitoring a pressure threshold of the insole pressure sensor, and transmitting an output signal when the pressure exceeds a pre-determined pressure threshold. The insole pressure sensor in various aspects has a ball portion and heel portion corresponding to the respective ball and heel of a subject's foot.

Abstract: A data bypass system for removing data traffic from a public switched telecommunications network designed for carrying voice traffic includes a remote access concentrator for receiving a modulated signal corresponding to the data traffic, demodulating the signal to recover the link layer frames that comprise the data traffic, and tunneling the link layer frames through a data network to a network access controller for extracting compressed data contained within the link layer frames, decompressing the compressed data, performing error correction, performing protocol processing, and transmitting the decompressed data to a data terminal device.

Abstract: A system and method provides network address translation as an external service for private networks. Given the fact that local office networks (i.e., stub networks) are typically assigned only one globally unique IP address (or a small set of addresses), the invention presents a novel service provider access server (e.g., router) which performs basic network address translation (NAT) and network address port translation (NAPT) for such networks. The system allows NAT and NAPT features to be removed from stub network routers, thereby significantly reducing the cost of Internet infrastructure to individual companies and organizations. NAT features on service provider's access servers provide the ability for multiple hosts in disparate private (unregistered) networks to utilize the services of a service provider, using a single global address for each private network and allow private networks to avoid renumbering with access to each new service provider.

Abstract: An Internet access system (10) incorporates an access control subsystem (12), implemented with a communications server (14), one or more Remote Authentication Dial In User Service (RADIUS) servers (16), and a remote access server (18) in network 21. Users are connected to the network by dial-up connections (22) through the communications server (14). When user (22) logs in through the communications server (14), RADIUS client software (45) first determines if user (22) is authorized by checking his password utilizing user profiles (46). The user profiles (46) also identify a filter "F(Timmy)". The RADIUS server (16) supplies the filter identification through the RADIUS client (45) for use by client software (44) for controlling access by the user (22) to Internet sites. The client software (44) then checks to see if the filter "F(Timmy)" is stored locally in cache (50). If it is, the client software (44) uses it for controlling access.
