摘要： An exercise device featuring a pair of knee joints, each pivotally and respectively coupled to a pair of calf linkages, each of the pair of calf linkages having a foot pedal at an opposite lower end that supports low impact user-defined natural exercise gait patterns. The knee joints are supported and directed to travel by linkage and/or carriage systems that operate substantially below a user hip area and direct the knee joints in a variety of travel paths, ranging from a constant arc, a linear pathway, to a variety of irregular arc shaped paths to pathways that may change during use. A secondary system coupled to the linkage and/or carriage systems provides lift and dampening forces to influence a responsiveness of the foot pedals via bending and straightening of the calf linkage about the respective knee joint, yet does not restrict back and forth travel of the respective knee joint.

摘要： A direct connect telephone line interface which includes a solid state off hook phone line load is disclosed. The solid state off hook phone line load utilizes an active semiconductor device coupleable between the phone lines, with the control input to the active semiconductor device being coupled to a bias circuit operative from the voltage across the phone lines to bias the active semiconductor device in saturation as a result of an answer voltage on the phone lines. The bias circuit is frequency selective so that the bias point of the active semiconductor device is substantially independent of information signals on the telephone line. Thus the active semiconductor device, in combination with any impedance in series therewith to set the desired answer load on the telephone lines, provides the desired load impedance on the lines to maintain the connection, but at the same time provides a very high impedance to the AC signals (communication signals) on the line so as to not attenuate the communication signals subsequently coupled to an isolation transformer. This allows the reduction in the size of the isolation transformer normally used in such interfaces without requiring a separate, relatively large holding coil.
摘要翻译：公开了一种包括固态脱钩电话线路负载的直连电话线接口。固态脱钩电话线路负载利用可在电话线路之间耦合的有源半导体器件，其中有源半导体器件的控制输入被耦合到偏置电路，该偏置电路从电话线上的电压起作用以将有源半导体器件偏置为饱和作为电话线上的应答电压的结果。偏置电路是频率选择性的，使得有源半导体器件的偏置点基本上与电话线上的信息信号无关。因此，有源半导体器件与任何与串联的阻抗相结合以在电话线上设置所需的应答负载，在线路上提供所需的负载阻抗以维持连接，但是同时提供非常高的阻抗交流信号（通信信号），以便不衰减随后耦合到隔离变压器的通信信号。这允许在这种接口中通常使用的隔离变压器的尺寸减小，而不需要单独的相对较大的保持线圈。

摘要： An acoustic coupler such as commonly used to receive and transmit data between computer terminals over telephone lines. The acoustic coupler is constructed in two halves joined by a flexible hinge which permits the two halves to move laterally and rotationally (about the hinge) with respect to each other. Each half of the acoustic coupler is also provided with a strap for securing the telephone handset portion in place upon the acoustic coupler halves. Once secured in place the telephone handset portion can be used as a "handle" to pick up and move the acoustic coupler from place to place. One half of the acoustic coupler contains a speaker, the other half contains a microphone, which may be electrically coupled to one another by electrical paths passing through, or forming a part of, the flexible hinge member.

摘要： An Electronics Package for providing a low cost enclosure of good esthetic and functional character. The package is formed from an extrusion, preferably a plastic extrusion, having one or more pairs of slots on the inner surface thereof for receiving and supporting the edges of a printed circuit board. End caps on each end of the extrusion complete the enclosure with the end caps being retained in place by any of a variety of techniques. By fastening the printed circuit board or printed circuit boards to at least one of the end caps, no other circuit board retention within the central extruded section is required. The end caps may be configured so as to have openings to expose or make accessible switches, connectors and the like mounted on the printed circuit board or boards, or to provide access for an edge connector for connecting directly to the printed circuit board. Various embodiments are disclosed, including embodiments for packaging of modems and further including modem packages having adjustable muff spacing.

摘要： An exercise device with a pair of upper links coupled to a frame and a pair of lower links pivotally and respectively coupled to the upper links is provided. A pedal is received on a distal end of each of the lower links. A transfer system between the pair of upper links may include a first and a second pushrod, each with a first end pivotally coupled to each respective upper link and a second end opposite to the first end. A first and a second damper arm, each pivotally coupled to the frame, may be included, each damper arm receiving a respective pushrod. An actuator may be coupled to the first damper arm and the second damper arm, thus providing movement of the first and second pushrods to alter a resting position of the first and second upper leg links with respect to the frame.

摘要： A telephone line interface for direct connect telephone line connections characterized by low cost and minimal package size requirements. The telephone line interface utilizes a small signal transformer with a primary winding couplable to the line by actuation of a relay. A secondary winding of the transformer is coupled to an integrated circuit which performs the functions of ring detect and dial tone detect, and separation of the received signal and the transmit signal when transmitting and receiving simultaneously. Ring signal detection on the secondary side of the coupling transformer substantially reduces the size and cost of the ring detect circuitry, as the secondary of the transformer may be provided with over-voltage protection, whereas the line side of the transformer must survive particularly high surge voltages, thereby requiring high voltage isolation not obtainable by way of conventional integrated circuits. Other aspects and features of the invention are disclosed.

摘要： A microprocessor based telephone like device which includes all of the functions of any ordinary telephone, the functions of a data terminal and many additional functions to provide a highly useful voice and data communications and control device for both professional and personal use. The system generally includes a provision for direct connection and acoustic coupling to a phone line for ordinary voice communications or for data communications through a modem. A full alphanumeric keyboard coupled with a significant buffer memory and a one line display in the terminal provide for buffering of incoming and outgoing data as well as the display thereof. Inasmuch as the microprocessor based system is a bus oriented system, a great variety of controllers and communications devices and interfaces may be coupled thereto to provide a large array of data and voice communications and control capabilities.
