摘要:
A rotary electrical actuator for mounting to a support surface in industrial applications having integral electronics that are isolated by vibration isolators from vibrations. The rotary actuator comprises a stator housing supporting a lamination stack and coils. The actuator housing has a mounting structure for mounting to the support surface (such as the mounting surface of an engine or a turbine for example) for support thereby. A rotor is carried for rotation in the stator housing. The actuator further comprises an electronics housing containing the electronics that control output of the electrical actuator. Vibration isolators supported by the stator housing in turn support the electronics housing, whereby vibrations received at mounting structure and traveling through the stator housing are dampened prior to traveling to the electronics housing. A number of embodiments are disclosed utilizing a tie rod assembly concept for the vibration isolators.

A shock absorber for a shaft. The shock absorber comprises a collar having an opening receiving the shaft. A clearance gap is defined between the collar opening and the shaft. A pin offset from the axis connects the collar to a shoulder on the shaft. A resilient o-ring arranged in the clearance gap engages the collar and the shaft. In operation, the collar and the shaft rotate in unison. However, when the collar accelerates or comes to a sudden stop, the resilient o-ring compresses to provide the shock absorption. The shock absorber may be incorporated into a rotary actuator. In a rotary actuator, the collar includes a stop tab that rotates between two stop surfaces of the actuator housing. When the stop tab strikes one of the stop surfaces, the resilient member compresses thereby absorbing and reducing impact force. Compression in the resilient member is snubbed via mechanical stops.

A low cost camera by implementing the major functions in host software is provided. This is accomplished by sending raw, digitized data from the camera directly to the host. The increased volume of raw data is handled by either an improved compression/decompression scheme using lossless compression, using lossy compression or using a shared bus with higher bandwidth. By moving such functions as color processing and scaling to the host, the pixel correction can also be moved to the host. This in turn allows the elimination of the frame buffer memory from the camera. Finally, the camera can use a low cost lens by implementing vignetting, distortion, gamma or aliasing correction with a correction value stored in a register of the camera for later access by the host to perform corrections.

A dispenser connectable to a source of high fluid pressure and including a housing having therein a three-position cylindrical valve which controls both a main passageway and an auxiliary passageway. The main passsageway extends through the housing and the cylindrical valve. The auxiliary passageway extends from the main passageway, through the cylindrical valve, through a passageway between the housing and cylindrical valve, through a fluid reservoir on the bottom side of the housing. The cylindrical valve is manually rotatable by a control knob to an "off" position where the main passageway is closed, to a "soap" position where both the primary and auxiliary passageways are open, dispensing fluid such as soap from the reservoir, and lastly, to a "rinse" position where the primary passageway is open and the auxiliary passageway is closed.
摘要:
A system and a method for the transfer of data between a digital camera and a host using a novel combination of hardware and software related elements. An aspect of the hardware-related elements provides a camera base unit which remains connected with the host, and which the camera is connected with to facilitate the transfer of data to the host. The camera base unit significantly simplifies the connection between the camera and the host by alleviating the need to directly connect the camera with a host. Furthermore, the camera base unit, by providing a pass-through connection and placement guides that mate with the camera, assures that an intuitive placement of the camera on the camera base unit also enables an electronic connection between the camera and the host. Therefore, the simple placement of the camera in contact with the camera base unit ensures a proper interface between the camera and the host, which is connected with the camera base unit. Another aspect of the hardware-based elements is directed towards a “quick send” button. Pushing the “quick send” button causes all the selected on-camera data to be transferred to a local or remote host. The transfer of data is caused by a series of software operations which are initiated in response to the camera connecting with the camera base unit, and which are performed either automatically or following the pushing of the “quick send” button.

A rechargeable self-contained deodorizing toilet seat is provided for installation on any standard toilet to remove bathroom odors. The seat is substantially the same in size and appearance as a standard toilet seat. Air conduits pass though the right and left sides of the seat member from the lower surface to the outer surface. The conduits contain activated carbon air filtration media and blowers for moving the air. Seals on the lower surface seal the seat to the toilet rim except at the front where ducts are provided for the introduction of fresh air. Lips on the inner edges of the ducts deflect air down into the bowl. The blowers are rotated by direct current electric motors powered by rechargeable batteries. Operation of the motors is controlled by switches which close only when the lid is raised and weight is placed on the seat. An electronic timer turns off the air filtration system after a preset period of time to conserve the battery power.

A fluid drive assembly for a rotary brush. A fluid inlet and a nozzle are included for dispensing fluid. A waterwheel is mounted for rotation about an axis. A rotary brush rotating means is rotatably driven by the waterwheel. The waterwheel has a series of vanes peripherally disposed around the waterwheel. Each vane has a wall for receiving the dispensed fluid having a pair of unrestricted ends spaced apart in a direction transverse to the direction of rotation and a fluid diverter separates the unrestricted ends diverting the fluid striking the walls simultaneously toward the unrestricted ends.

An apparatus (20, 30) operative from a first liquid pressure only and configured to generate and selectively direct a stream of first liquid or a third liquid is disclosed. Since no electrical power is used, the apparatus can be safely operated in any moist environments (e.g. a shower). In preferred embodiments, the apparatus is configured to operate in series with a showerhead (22) and a sink tap (32) for dental irrigation. Either water or dental solution which is comprised of water mixed with dental concentrate, can be independently selected. A mixer valve (48) controls the concentration of the irrigating solution. A handheld syringe (40) contains all other controls necessary for operation.
