Abstract: A bicycle hydraulic disc brake having opposing caliper pistons riding in a pair of opposing caliper cylinders. Each caliper piston is configured to advance a brake pad operatively associated therewith into contact with a disc operatively received therebetween upon delivery of pressurized hydraulic fluid to the respective opposing caliper cylinder. A master cylinder is configured, upon actuation, to deliver pressurized hydraulic fluid to the caliper cylinders. An equalizer is provided in fluid communication with the caliper cylinders, the equalizer being configured to provide an equal volume of pressurized hydraulic fluid to each caliper cylinder upon actuation of the master cylinder.

Abstract: A bicycle frame includes a substantially rigid front frame portion and a substantially rigid rear frame portion. A link is connected to the rear frame portion by a first pivot and to the front frame portion by a second pivot. A frame segment is rigidly connected at a first end to one of the rear frame portion and the front frame portion and pivotably connected at a second end to other of the rear frame portion or the front frame portion by a third pivot. The frame segment is flexible proximate the second end.

Abstract: A master cylinder lever for a hydraulic disc brake comprises a lever pivotally connected to a master cylinder housing and a bar clamp attached to the master cylinder housing for attaching the master cylinder housing to a bicycle handle bar along a longitudinal clamp axis. A cylinder wall is associated with the master cylinder housing, the cylinder wall comprising a cylinder interior and a cylinder exterior extending axially of a cylinder axis. A reservoir is associated with the master cylinder housing and is in fluid communication with the cylinder interior through a port in the cylinder wall. The reservoir comprises only a radial portion of the cylinder exterior. A piston within the cylinder has a seal operatively associated therewith.

Abstract: A hydraulic disc brake master cylinder having a bar clamp attached to a master cylinder housing allowing the attachment of the master cylinder to a handle bar along a longitudinal clamp axis. The master cylinder also includes a cylinder wall associated with the master cylinder housing extending axially along the cylinder axis. The cylinder axis is not parallel to the longitudinal clamp axis. This embodiment further includes a reservoir for hydraulic fluid which includes a first wall which first wall includes only a radial portion of the cylinder exterior. The reservoir also includes an elastomeric diaphragm. The cylinder axis and the longitudinal clamp axis lie in a plane substantially bisecting the first wall. Thus, the symmetric master cylinder lever may be disposed on either the right or left portion of a handle bar without effecting operation of the master cylinder lever by a user.

Abstract: A method of varying a rest position of a one-piece lever in a hydraulic brake system. The hydraulic brake system comprises a master cylinder including a cylinder and a port, a piston received in the cylinder, the piston having a radial seal between cylinder and the piston, the piston being movable within the cylinder by a one-piece lever operatively associated therewith to selectively pressurize hydraulic fluid within the cylinder by closing the port. The hydraulic brake system further comprises a caliper in fluid communication with the master cylinder, the caliper having a pair of brake pads operatively associated with the disc received therebetween. The caliper is actuated by movement of the one-piece lever in an arc between a rest position and an engagement point with the pads in engagement with the disc. The length of the arc is variable by movement of the engagement point relative to the rest position along the arc.

Abstract: An infrared thermometer has an elongate housing extending along an axis with an actuator at one housing end, the actuator being actuated by engagement along the axis. The housing further includes an opening at one end and a temperature sensor operatively associated with the opening. The temperature sensor can be advanced from a retracted position within the housing to an extended position operatively associated with the opening for sensing the temperature of an object. As the sensor moves between the retracted and the extended position, the sensor changes from a dormant state to a sensing state.

Abstract: A master cylinder for a bicycle hydraulic disc brake includes a cylinder wall defining a cylinder interior and a cylinder exterior. A piston is received within the cylinder interior. A reservoir for hydraulic fluid is defined in part by a portion of the cylinder exterior, the portion of the cylinder exterior protruding into the reservoir. A port through the portion of the cylinder exterior which protrudes into the reservoir provides fluid communication between the reservoir and the cylinder interior. The port is located on the portion of the cylinder exterior which protrudes into the reservoir at a position which prevents air bubbles within the reservoir from entering the port.

Abstract: The apparatus and method for high speed data and command transfer over an interface (202), such as an ISA or PCMCIA bus or interface, includes a transceiver (206) and a processor (210) having a direct memory access (DMA) controller (240), a memory (211) for storage of data, and a channel interface (218) for connection to a communications channel. The processor (210) is responsive through a set of program instructions, such as software or firmware, to receive an interrupt signal (310, 315) and, when the interrupt signal indicates a write command (320, 330), to transfer data via the transceiver from the interface to the memory for transmission over the communications channel (335), and when the interrupt signal indicates data received from the communications channel (350), the processor further responsive to generate a read command and transfer data from the memory to the interface via the transceiver (355).
