An electronic product (10) includes a front housing (12) coupled to a first frame (32) having a first frame guide rail (34), a rear housing (14) coupled to a second frame (42) having a second frame guide rail (54), a pivot arm (50) coupled between a fixed axis (33) on the first frame and a first translating axis (45) on the second frame, and a second translating axis (46) that translates along the first frame guide rail as the first translating axis translates along the second frame guide rail. The fixed axis and second translating axis are in substantially the same horizontal plane when the electronic product is in a closed position. The fixed axis and first translating axis are in substantially the same horizontal plane when the electronic product is in a closed position and in substantially the same vertical plane when the electronic product is an open position.

The embodiments of the invention concern a keypad (120). The keypad can include a membrane (143), at least one key with at least one flange 150 to overlap with at least one second flange of a second key (146), and at least one audio port opening (107) in the membrane for providing a passage of air from a transducer (101) positioned behind at least one key through the keypad to a main volume area (112). For example, the audio port opening can be in a region of the membrane between the keys, and the overlapping of the flanges obscures a view of at least one audio port opening.

A sensing method and apparatus using photonic band gap multilayered material. Photonic band gap multi-layers are formed from alternating layers of higher refractive index and lower refractive index materials, and may be deposited or disposed on a optically transparent substrate or a reflecting face of a prism. Light is directed into the prism, directed to the photonic band gap multilayer, and reflected out of the prism, where it is captured and analyzed. Various sensor configurations keep light wavelength or coupling angle fixed, while monitoring the change in the other parameter. Also disclosed is a microarray configuration with an array of probe spots placed on one surface of the multilayer, which is mounted on an x-y translation stage.

A packaged core is obtained using a conventional core barrel system. A lining is provided in the core sample container of the core barrel. The core barrel is connected to a drill string extending into a borehole. As the drill string is rotated, the core sample moves into the sample container and inside of the lining. When the core barrel arrives at the surface, the sample core may be removed from the core barrel packaged in the lining. The core may be examined on site or the ends of the lining closed and the core completely packaged for shipment to the laboratory.

A variable purge orifice assembly for an evaporative emission system of a vehicle includes a housing for fluid connection to a vapor canister and a purge solenoid of the evaporative emission system. The housing has a purge orifice therein. The variable purge orifice assembly also includes a regulating device connected to the housing and for connection to an engine of the vehicle. The regulating device is actuated by manifold vacuum from the engine to vary flow of fuel vapor through the purge orifice from the vapor canister to the purge solenoid.

The decontamination of PCB-containing transformers to obtain treated transformers containing less than 50 parts per million (ppm) polychlorinated biphenyls (PCB) can be achieved using a method wherein the transformer is initially drained of all PCBs; then the core/coil assembly is removed. The internal surfaces of the transformer are then cleaned using a solvent. Finally, a new core/coil assembly is installed. The method is simple and can be completed within a substantially shorter period of time than methods known in the art.
摘要:
Nitrate-polluted run-off water from a field is conveyed via land drains to a reservoir. The reservoir is large enough to contain excess quantities of storm water from the field. From the reservoir, the run-off water enters a tank which contains wood or other organic carbon material. The wood is kept under water, i.e. under anaerobic conditions, whereby the nitrate is broken down by bio-chemical action. Sufficient wood is provided, and the flow rate is so adjusted, that the nitrate-polluted water spends many hours in contact with the wood.

A manipulator joint includes an encoder having a body and shaft. The encoder body may be fixed to a first housing and the encoder shaft may be fixed to a second housing. The second housing is separate from, distal to, and rotatable with respect to the first housing. Rotation of the second housing may be about a common axis shared with the first housing. A hollow driveshaft, rotatably coupled to the second housing, extends across the joint from the second to the first housing. A torque limiter may be fixedly coupled to the second housing and releasably coupled to the driveshaft. The encoder may be configured to output an absolute angular position of the first housing with respect to the second housing. A method of detecting an over-torque condition of the manipulator joint includes transmitting commands from a processor to the drive motor and receiving data from the encoder.

A housing assembly (100) provides a device housing (102) having an outer surface (104) and having a compartment (106). A door (108) can be movably coupled to the housing where the door can be movable from a closed position through an open position. The door can at least partially enclose the housing compartment in the closed position. The housing assembly also provides a biasing member (110) biased against the door to move the door to the open position. In another embodiment, a housing assembly (200) can also include a frame member (201) designed to be removably interlockable with the housing assembly and a door (208) movably coupled to the frame member.
