Patent number: 6810436Abstract: The present invention provides a wireless receiving device jointly used by computer peripherals and a method thereof. The wireless receiving device comprises a wireless receiving circuit, a micro-processing circuit, and an interface circuit. The micro-processing circuit can receive wireless signals emitted by wireless emitting devices of different computer peripherals via the wireless receiving circuit, and has a learning procedure. The learning procedure can be activated to let the micro-processing circuit memorize and lock on a specific wireless emitting device. The signal processed by the micro-processing circuit is then transferred to a computer via the interface circuit.Type: GrantFiled: October 30, 2001Date of Patent: October 26, 2004Assignee: Topseed Technology Corp.Inventors: Kun Chan Wu, Wen Sheng Liao, Chao Wu Chien, Chung Ping Chi

Patent number: 5059072Abstract: A trailer hitch (1) for use on a railcar (C) is movable between an erect position and a retracted position. A first strut (9) has its lower end pivotally mounted to the railcar. A second strut (25) has its lower end movable in a horizontal direction relative to the railcar. A hitch head (3) is carried on the upper ends of the struts for engaging a trailer loaded on the railcar to hold it in place. A cushioning unit (49) is carried by the second strut to cushion the trail from impacts. A latching mechanism (57) automatically latches the hitch in its erect position and maintains it there. The latching mechanism also allows for a safe release of the hitch so it can be retracted.Type: GrantFiled: July 9, 1990Date of Patent: October 22, 1991Assignee: ACF Industries, IncorporatedInventor: Jan D.

Patent number: 5015131Abstract: A retarder (97) for a railcar hitch (1) is disclosed. The hitch has an erected and a retracted position and the retarder slows movement of the hitch towards its retracted position. The retarder comprises a cylinder (99) fixedly mounted on a railcar. A piston (101) is movable in the cylinder. A rod (115) attaches the piston to the movable hitch element so that preferably only axial loads act on the piston during operation of the hitch. The fluid compressed in one end of the cylinder by the piston is bled (metered) from the one end of the cylinder so as to control the rate of movement of the movable element during hitch retraction.Type: GrantFiled: September 19, 1989Date of Patent: May 14, 1991Assignee: ACE Industries, IncorporatedInventors: Kenneth D. Schmidt, Jan D. Holt

Patent number: 5004386Abstract: A protective cover (163) for a trailer hitch (1) for use on a railcar (C). The hitch has a support (7), a hitch head (3) carried by the support, a locking mechanism (49) for latching the hitch in an upright, erect position, and a release mechanism (90) for allowing the hitch to retract. The cover comprises a plate (165) substantially covering at least a portion of the support, the locking mechanism, and the release mechanism. One end of the plate is pivotally mounted relative to the railcar and the other end of the plate cammingly engages the hitch support so that as the hitch is erected and retracted, the plate moves with the support and covers at least a portion of the support, the locking mechanism and the release mechanism.Type: GrantFiled: October 2, 1989Date of Patent: April 2, 1991Assignee: ACF Industries, Inc.Inventors: Kenneth D. Schmidt, Jan D. Holt

Patent number: 4723879Abstract: An elastomeric in compression trailer hitch cushion for an over-the-road trailer hitch, as mounted on a railway car, is disclosed so as to cushion against longitudinal loads transmitted between the railroad car and the trailer. This trailer hitch cushion serves as the hitch diagonal strut and it has one end thereof secured to the railway car and its other end secured to the vertical hitch strut, with the diagonal cushioning strut being disposed so as to cushion longitudinal loads in either fore or aft direction and to maintain the vertical strut in vertical position. The cushioning strut comprises a frame, compressible elastomeric cushioning members carried by the frame, and a compression load applying system for compressing the elastomeric members relative to the frame upon a longitudinal load in either fore or aft directions relative to the railroad car being applied to the hitch.Type: GrantFiled: April 10, 1986Date of Patent: February 9, 1988Assignee: ACF Industries, IncorporatedInventor: Jan D.
