A bit retention device has an upper support member having an inner surface and an outer surface. A lower support member fixed to the upper support member. A stationary plate is mounted to the inner surface of the upper support member. A clamp plate opposes the stationary plate and is spring biased toward the stationary plate and slidably moveable between the upper support member and the lower support member.

A product management display system for merchandising product on a shelf includes using a trackless pusher mechanism that travels along a surface on which product is placed and one or more dividers for separating product into rows. The one or more dividers may be engaged to a front rail in two different conditions, locked and unlocked. In a locked condition, the relationship between the divider and the front rail resists alteration in any direction with respect to each other. In the unlocked condition, the dividers may be freely slid laterally along the front rail, while remaining perpendicular to the front rail. The one or more dividers may lock to the front rail through the use of corresponding teeth, resilient surfaces, a locking tab, a locking bar and/or a cam.

A prosthesis device can include a socket or a kit for forming a socket having a lanyard suspension system. In one example, the lanyard suspension system includes a tightening device having a housing, and tightening the lanyard gathers a tensioning line portion of the lanyard into an interior of the housing.

An energy absorber includes a monolithic length of ductile material comprising a first end and a second end. The material is formed to include at least a first longitudinally extending section that extends continuously between the ends, a first discontinuous section extending longitudinally from the first end toward the second end and at least a second discontinuous section extending longitudinally from the second end toward the first end. The first longitudinally extending section is deformed over at least a portion thereof out of a plane running through both ends. The first discontinuous section and the second discontinuous section are connected such that tensile force of a threshold magnitude is required between the ends to disconnect the first discontinuous section from the second discontinuous section, letting the first longitudinally extending section free to deform under tensile force and extend in longitudinal direction.

Various exemplary methods and devices for actuating surgical instruments are provided. In general, a surgical device can include one or more actuation shafts configured to facilitate actuation of the device. In an exemplary embodiment, the device can include four actuation shafts, two actuation shafts to facilitate articulation of the device, one actuation shaft to facilitate opening and closing of jaws at a distal end of the device, and one actuation shaft to facilitate moving a cutting element of the device. In an exemplary embodiment, each of the one or more actuation shafts can include a distal elongate member and a proximal elongate member having a proximal end attached to a distal end of the distal elongate member. The proximal elongate member can be rigid, and the distal elongate member can be flexible.

A brake including an adjustable thrust element for applying a brake force to a brake pad and an adjustment device for selectably adjusting the thrust element. The adjustment device includes a shaft having a cylindrical shaft surface, a sleeve having a cylindrical sleeve surface, wherein the shaft and the sleeve are arranged end-to-end, and a torque clutch including a wrap spring that is mounted on the cylindrical shaft surface and mounted on the cylindrical sleeve surface, the shaft including an integral drive pin for selectively rotating the shaft. The brake further includes an operating lever, wherein the drive pin extends radially directly from the shaft surface of the shaft and wherein the operating lever includes a groove that receives the drive pin.

An endoluminal device can comprise a flexible tubular wall and a frame member. The frame member can be comprised of a shape-memory material having sides with protrusions which are partially or substantially flattened when formed together with the flexible tubular wall to thereby create a bias in the side wall of the endoluminal device that resists deformation from a desired device profile during crush loading and is thereby resistant to invaginations when deployed.

A method includes mapping a contoured surface of at least one bone onto a digital model of a resection guide locator using a processor to create a digital model of a customized resection guide locator and manufacturing the customized resection guide locator. The customized resection guide locator includes a complementary surface of the at least one bone and a wall having a shape that is complementary to an outer profile of a resection guide and defining a pocket. A first elongate slot and at least one first hole are positioned within the pocket such that the first elongate slot aligns with a second elongate slot defined by the resection guide and the at least one first hole aligns with at least one second hole defined by the resection guide when the resection guide is received within the pocket of the customized resection guide locator.

An electronic device includes an electronic circuit board containing a processing element and a vision sensor. A carrier frame is used to support the electronic circuit board. An optical element is positioned over the sensor and supported by the carrier frame. The electronic circuit board is bent to reduce the length, thickness and/or width of the electronic device, without increasing the others of the length, thickness and/or width of the electronic device.
