Abstract: Exemplary power systems for dynamically controlling a dispenser drive motor for dispensing soap, sanitizing or lotion. An exemplary soap, sanitizing or lotion dispenser includes a housing, a receptacle for receiving a container for holding a soap, sanitizing or lotion, a container of soap, sanitizing or lotion and a pump secured to the container. The exemplary soap, sanitizing or lotion dispenser includes a power source, a motor and an actuator that couples the motor to the pump. In addition, the exemplary soap, sanitizing or lotion dispenser includes pulse width modulation circuitry in circuit communication with the power source and the motor. Movement of the actuator one actuation cycle dispenses a dose of soap, sanitizing or lotion. The pulse width modulation circuitry provides a plurality of voltage pulses to the motor to move the actuator one actuation cycle.

Abstract: A surgical instrument includes an anvil and an elongate channel. The elongate channel includes a plurality of first electrical contacts and a plurality of electrical connectors comprising a plurality of second electrical contacts, wherein the electrical connectors are spring-biased such that a gap is maintained between the first electrical contacts and the second electrical contacts. The surgical instrument further includes a staple cartridge releasably attachable to the elongate channel, wherein the staple cartridge has a cartridge body comprising a plurality of staple cavities, a plurality of staples deployable from the staple cavities into the tissue, and a plurality of third electrical contacts, wherein the attachment of the staple cartridge to the elongate channel moves the electrical connectors causing the second electrical contacts to bridge the gap and become electrically coupled to the first electrical contacts.

Abstract: A chassis for telecommunication gear including horizontal circuit boards includes an enclosure forming a front-accessible circuit board slot for receiving horizontal circuit boards. The circuit board slot has first connectors for receiving mating second connectors on the circuit boards, and multiple circuit board guides for guiding and securing horizontal circuit boards inserted into the slot. Adjacent pairs of the guides are spaced to receive circuit boards of predetermined widths, and at least one of the guides is removable so that it can be re-positioned within the slot for changing the spacing between adjacent pairs of the guides to receive circuit boards of different widths. The circuit boards may be telecommunication line cards.

Abstract: A method of preventing curved-side containers on a conveyor belt of a commercial filling line from slipping across and past the curved surface of the forward container by providing a small flat area on opposing sides of the containers and positioning the containers in the filling line to cause the flat areas on one container to register with the flat areas on adjacent containers in the line, and a product container having curved sides with wider shoulders tapering to a narrower base, with a small flat area on each side of the container at the widest point on the container shoulders.

Abstract: An electronic unit with a mother board carrier beneath a service carrier in a housing. The carriers are independently movable between retracted use positions and forward access positions for maintenance. Service components are hence of no hindrance when removing printed circuit boards from the mother board carrier. The mother board is horizontal with the primary surface facing upwards. This latter feature together with the orientation of other printed circuit boards and of the service components minimizes the frontal area of the unit and provides pathways for front-to-rear cooling air flow. A connector arrangement connects the two carriers together only when both carriers are in their retracted use positions. Flexible lengths of cable extending between the carriers together with attendant stowage and hindrance problems are thus avoided. A retaining bar structure is included which acts at multiple positions against daughter boards to hold them securely against vibration during transporting and also in use.

Abstract: A telecommunications rack is provided to house telecommunications equipment, to conform to standards set by NEBS and ETSI, and provide the advantages of a lightweight rack while remaining stiff. This rack has two upright supports wherein each upright support has a truss member secured to vertical members. The truss configuration permits easier access to cabling and reduces the weight of the rack. The rack also incorporates a base with adjustable feet for improved levelling after the rack is installed. The base also may be pre-stressed, which is advantageous in locations that are susceptible to seismic occurrences to reduce the risk of damaging the telecommunications equipment during such occurrences.

Abstract: A heat conductor has a plurality of resilient elongate elements, each being connected to a surrounding base of the conductor through two neck portions and being pivoted about its common axis. Two end portions of each elongate element are curved. When the heat conductor is mounted on a heat sink which is held over a plurality of electronic components mounted upon a printed circuit board, the curved end portions contact both the components and the heat sink with an appropriate pressure, because of the torsional action of the neck portions. The elongate elements provide short thermal paths to directly conduct the heat generated by the components to the heat sink.

Abstract: An environmental protector for electronics devices in outside terminal boxes. The protector has a laminate wall which provides a moisture barrier, penetration resistant surface and EMI shield. The protector may be flexible or substantially rigid and is in the form of an open-ended container for receiving an electronics device. The container is sealed at the open end around a connector unit of the device with outgoing terminals accessible for connection purposes. The device may be potted within the container. Conveniently, the EMI shield is connected to ground by a ground element in the connector unit.
