    摘要： A barrier movement operator with a backup source of DC power is disclosed. The power supply of the barrier movement operator sends current limited DC to the backup which uses the DC to charge a battery. The battery is in circuit at all times with the barrier movement operator power supply by means of a power diode and, when an AC mains power failure occurs, DC power is sent from the battery to power the barrier movement operator.

    摘要： Methods and apparatus for controlling the speed of an A.C. induction motor are disclosed and shown in operation for controlling the movement of a barrier. Included are voltage configuration circuits which selectively gate portions of the half-cycles of AC mains voltage to the induction motor. When the motor is started increasing amounts of mains AC voltage is applied to the motor and decreasing portions of the mains AC are applied to the motor during a stopping routine. The motor can also be energized with less than full mains AC to permit differences in barrier movement speed dependent on operating parameters.

    摘要： A wireless transmit-only apparatus (20) has a controller (21) that responds to a user interface 25 by correlating specific user input with a corresponding characterizing transmission parameter(s) as is stored in a memory (35) and by selecting a corresponding resonant device (31 and 32). The latter devices serve to drive the PLL control input of a phase locked loop (23) to thereby influence the transmission carrier frequency of a wireless transmitter (22). In a preferred embodiment, at least one of the resonant devices comprises a mechanically resonant device such as a surface acoustic wave device, a crystal resonator, or a ceramic resonator.

    摘要： A method for controlling an optical, path-to-sight link, the optical link including a source of light having a beam of light, a controllable beam steering device and an actuator to permit steering the light beam, the beam steering device being controllable by predetermined control signals. The method includes the following steps. The beam steering device is controlled so as to scan the beam of light in a first predetermined pattern. First direction is received data from a remote receiver including a light detector, the direction data corresponding to a direction of the beam at which the scanned beam of light is detected by the light detector. Responsive to the first direction data, a first beam direction is determined for data communication from the link to the receiver. The beam steering device is controlled to maintain a communications beam direction corresponding to the first beam direction. The beam of light is modulated with electronic signals.

    摘要： A user's set top box (STB), or other client, executes a shell and has an application program interface (API) by which certain features of the client can be controlled. The client is in communication with a walled garden proxy server (WGPS), which controls access to a walled garden. The walled garden contains links to one or more servers providing network-based services. The client sends a request to the WGPS to access a service provided by a site in the garden. To provide the service, the site sends the client a message containing code calling a function in the API. The WGPS traps the message from the site and looks up the site in a table to determine the access control list (ACL) for the site. The ACL is a bit-map that specifies which functions of the client's API can be invoked by code from the site. The WGPS includes the ACL in the header of the hypertext transport protocol (HTTP) message to the client. The shell receives the message and extracts the ACL. The shell uses the ACL to determine whether the code has permission to execute any called functions in the API. If the code lacks permission, the shell stops execution and sends a message to the site indicating that the site lacks permission. Otherwise, the shell allows the code to call the function.
