Abstract: The lock with key having expanding arm elements is a lock. The lock with key having expanding arm elements comprises a body structure and a key structure. The key structure inserts into the body structure. The key structure rotates within the body structure to release the locking elements of the lock with key having expanding arm elements. The key structure comprises a plurality of rotating blade structures. Each of the plurality of rotating blade structures interact with an independent lock mechanism selected from a plurality of lock mechanisms contained in the body structure. The rotation of each rotating blade structure within its associated independent lock mechanism releases the locking elements of the lock with key having expanding arm elements.

Abstract: The lock with key having expanding arm elements is an electromechanical lock mechanism. The lock with key having expanding arm elements comprises a key structure, a lock structure, and a lock control circuit. The lock structure is a fastening device. The lock structure secures the position of a first object relative to a second object. The lock structure is a releasable structure such that the position of the first object relative to the second object can be adjusted after the lock structure is released. The lock control circuit is an electric circuit. The lock control circuit forms an electronic locking mechanism that fastens and releases the locking structure. The key structure is a multi-blade structure that controls the operation of the lock control circuit.

Abstract: A power distribution system is releasably secured to a power distribution panel, and includes a circuit breaker to detect a fault condition and to automatically move a circuit breaker switch from the ON position to the OFF position. The power distribution system further includes a backplane connector to provide connection to the power distribution panel and an interconnect mechanism to connect the circuit breaker to the backplane connector when the circuit breaker is moved from a disengaged position to an engaged position with respect to the backplane connector. The power distribution system further includes a guard coupled to the interconnect mechanism and configured to cover portions of the enclosure of the circuit breaker. The guard further prevents the circuit breaker switch from moving from the OFF position to the ON position until the interconnect mechanism connects to the circuit breaker to the backplane connector.

Abstract: An electrophotographic printer includes a charge roller in charge-transferring relation to a photoconductive imaging portion. The printer may determine an AC voltage setpoint of the charge roller.

Abstract: A device includes a charge roller and a control portion. The charge roller is removably insertable to be in charge-transferring relation to, and spaced apart by a first air gap from, a photoconductive imaging portion of an electrophotographic printer. The control portion is to determine a size of the first air gap based on determination of a charging threshold voltage associated with the charge roller.

Abstract: One example of a display device includes a first layer and a second layer including a conductive material. The second layer is attached to the first layer such that a surface of the second layer facing the first layer is exposed along an edge of the second layer. The second layer supports an electronic paper display imageable by receiving charges on an imaging surface of the electronic paper display. The second layer is electrically coupled to a counter-electrode of the electronic paper display.

Abstract: One example of a display device includes an electronic paper display, a counter-electrode, and a floating electrode. The electronic paper display is imageable by receiving charges on an imaging surface of the electronic paper display. The counter-electrode is opposite to the imaging surface of the electronic paper display. The floating electrode is capacitively coupled to the counter-electrode.

Abstract: A double shutter shroud (5) and a flexible sheath (11) surrounding a stab (10) of an MCC unit, form a protective tunnel (30) for the stab to connect to a bus 4. A first shroud (6) mounted on the bus, includes a first gate (12). A second shroud (20) mounted on the MCC unit includes a second gate (24). When the MCC unit slides into an MCC section, a unit key (16) opens the first gate. When the stab is advanced toward the bus, a stab key (28) opens the second gate, forming a protective tunnel (30) from the flexible sheath and through the first and second shrouds. The protective tunnel protects the stab and bus from contamination, helps prevent dielectric breakdowns and short circuits between different phase busses, and protects an operator from electrical hazard of touching the bus or stab with tools or fingers.

Abstract: A spring loaded, bistable connect/disconnect mechanism for a motor control center (MCC) unit 20, provides a secure and quick means to connect and disconnect the stab 30 of a MCC unit to a vertical power bus 24. The low profile mechanism comprises a series of flat links 6, 7, and 11 and an over-center spring 8 in the top of the MCC unit, for efficient use of space. The mechanism provides an additional force to quickly connect and disconnect the stabs to and from the power bus. The mechanism enables safe insertion and removal of the MCC unit from an MCC section, by incorporating interlocks 5 to prevent the MCC unit from being inserted when the stabs are extended and to prevent the MCC unit from being removed when the stabs are extended. Interlocks prevent the extension or retraction of the stabs when the handle is in an ON position.

Abstract: A single-use indicator is provided and is particularly well suited for use with a surgical catheter device. The indicator includes an absorbent filament or wick which is placed in a transparent or translucent indicator lumen of a multi-lumen catheter. The lumen is provided with at least one side port. When the catheter is inserted into a blood vessel, blood enters the indicator lumen through the side port and is absorbed by the filament, thus turning the filament red or purple in color. When the instrument is removed from the blood vessel, the stained filament is clearly visible as an indicator that the instrument has been used. Because the filament is trapped inside a lumen of a relatively long catheter, it is difficult or impossible to remove it during a remanufacturing process.

Abstract: Dual-section ultra-thin (0.1-0.8 mil) plastic produce bags having a large upper compartment with an open top boundary (fill opening) and a bottom boundary that is partially open to a smaller lower section. The bags are provided in a series on a roll enabling dispensing of each bag by unrolling and tearing along a line of perforations. Individual plastic bags are defined by lines of adjacent heat seals and perforations on a flattened plastic tube. Two elongated side straps have ends attached to the bag adjacent to the top opening so that the top opening of the bag may be closed by tying the straps together. The straps are generally trapezoidal in shape with the widest dimension of the trapezoid being 50-60% the width of the bag at the junction line of the strap to the bag. This design provides strength to the attachment of the strap to the bag in order that the straps may also be used as a handle for carrying the bag.
