摘要:
A pressure sensitive stylus including a writing tip that is movable in response to contact pressure applied on the writing tip, an extremity that is movable together with the writing tip, an elastomer element positioned between a surface of the extremity and a surface formed from a housing of the stylus and a displacement detector for detecting the displacement of the writing tip. At least one of the extremity, the surface formed from the housing, and the elastomer includes a surface with base portion and at least one protrusion extending out from the base portion. When operating the stylus, at least one protrusion contacts a facing surface over a first range of contact pressures and both the at least one protrusion and the base portion contacts the facing surface for pressures exceeding the first range of pressures.

A digitizer system comprises at least one object incorporating an electronic tag configured for radiating at least one modulated signal and at least one second signal; a digitizer sensor configured for detecting the at least one second signal while the object is positioned on or over the digitizer sensor; and circuitry configured for identifying the object based on modulation of the at least one modulated signal and for determining a position of the object on or over the digitizer based on the detected second signal on a portion of the digitizer sensor.
摘要:
An integral flexible diaphragm for a valve of the pilot type comprising a housing with a flow chamber and a control chamber connected by a pilot channel, and a control member for closing the pilot channel. The diaphragm separates the flow chamber from the control chamber and is disposed opposite a valve seat to control the flow through the valve. The diaphragm has a peripheral annular part and a central part both tightly fixed to the housing, and an intermediate annular part movable to close the valve seat. The pilot channel of the valve is obtained through the central part, so that a travel distance of the control member is independent of a travel distance of the intermediate annular part for closing the valve seat.

A digitizer system includes a stylus comprising a plurality of transmitters for transmitting signals, wherein each of the plurality of transmitters are distanced from one another by a defined distance, a digitizer sensor operable for sensing signals transmitted by the plurality of transmitters, and circuitry associated with the digitizer sensor for tracking a projected location on the digitizer sensor of each of the plurality of transmitters based on the signals sensed, and for tracking a geometric relationship between the projected locations.
摘要:
A valve of the pilot type comprising a housing with a circular cylinder end for mounting in a valve base. The housing has an inlet port, an outlet port, an internal cavity, and a flexible membrane dividing the cavity into a flow chamber and control chamber. The inlet port is in constant communication with the flow chamber, while the outlet port is in communication with the flow chamber via a valve seat formed in the housing opposite the membrane. The outlet port is formed at the face of the cylinder end. An annular seal is disposed on that face, around the outlet port, such that when the valve is mounted into the valve base, the seal is urged axially to a face of the valve base providing fluid-tight communication between the outlet port and an outlet opening in the valve base. The inlet port is formed at the lateral surface of the cylinder end, so as to provide inlet flow transverse to the axis of the cylinder end.
