Abstract: A bicycle helmet is disclosed having a flexible, articulated member being resiliently flexible to provide resilient forward pressure against an inwardly curved portion on the posterior of a wearer's head and a flexible connection between the articulated member and opposite sides of the shell assembly including at least one elastically elongatable strap portion for providing additional resilient forward pressure against the wearer's head.

Abstract: A coding system for various I/O module elements of an I/O cabinet assembly is disclosed which is able to identify analog, digital and control I/O modules by appropriate functional representation combined with a distinct color code found on the front of each module and to identify appropriate internal field wiring connections in the identified module by the module identifying color. Each module has a written identification such as A—for analog, D—for digital and C—for control, I—for input, O—for output combined with an appropriate color bar identifying the type of module. Thus process and terminal blocks forming and I/O unit are easily matched for assembly and are easily inserted into an I/O cabinet in the proper location.

Abstract: A unique cabinet mounted I/O assembly adapted for integration into a control system which allows a block I/O assembly to be mounted in both sides of the cabinet allowing a blind fit of power and signal connections insuring that power will be provided to the block I/O assembly before any application of signals thereto and preventing any mismatching of I/O units to wrong processor blocks in the cabinet by a color matching scheme.

Abstract: A bicycle helmet is disclosed having a flexible, articulated member depending from the rear of the helmet, providing a closer fit to an individual wearer's head and improving stability of the helmet on the head, particularly for mountain bike riding. The articulated member contacts the wearer's head beneath the occipital region and applies a forward and upward pressure against the head. The general embodiment of the invention includes an elastic strap stretching from one side of the helmet, across the back of the articulated member, to the opposite side of the helmet. Adjusting this strap allows the wearer to adjust the forward and upward pressure exerted by the articulated member on the wearer's head.

Abstract: The combination of a water filter and a display for indication of the water filter condition includes an electrical circuit connected to the display and responsive to use of the water filter. The circuit includes a microcontroller, a timer connected to the microcontroller and providing timing signals thereto, and a switch connected to the microcontroller and responsive to the flow of water from the filter to cause the microcontroller to process the timing signals. The microcontroller is programmed to utilize the timing signals to provide an electrical signal to the display indicative of filter condition.

Abstract: A faucet having multiple water discharges includes a housing, an input water connection for the housing, a stream discharge on the housing, a spray discharge on the housing, a filtered water discharge on the housing, a water filter within the housing, and a control valve in the housing connected to each of the water discharges. There is an unfiltered water flow path from the input water connection to the control valve. A manual actuator accessible from the exterior of the housing operates the control valve to direct water from the unfiltered water flow path to either the stream discharge or the spray discharge. There is a filtered water flow path from the input water connection, through the filter, to the control valve. A filtered water manual actuator accessible from the exterior of the housing operates the control valve to direct filtered water to the filtered water discharge.

Abstract: A water filter cartridge for use with a water faucet includes a cover and a filter element located within the cover. The cover has a single unfiltered water input connection and a pair of water output connections, one for filtered water and one for unfiltered water. There is a conduit within the cover connecting the unfiltered water input connection and the unfiltered water output connection. There is a flow path within the cover from said unfiltered water input connection, through said filter element, and connecting to said filtered water output connection.

Abstract: A water input connection for a faucet includes a body which has a water inlet and a water outlet. There is a chamber within the body and there is a seat adjacent the water inlet. An antisiphon check valve is movable within the body chamber toward and away from the seat to open and close the water inlet connection. There is an antiflow valve movable within the body to open and close the water outlet connection. A spring is positioned within the body and biases both the antiflow valve and the antisiphon valve toward water inlet and water outlet closing positions.
