A bipolar electrosurgical forceps comprises an elongated tubular barrel having a proximal end, a distal end and a lumen extending between these two ends. A handle is provided at the proximal end of the barrel and includes an actuating member for opening and closing a pair of forceps jaws that are mounted at the distal end of the barrel. The forceps jaws include cam slots in a proximal head portion thereof. A coupling member extends between the actuating member on the handle and the pair of forceps jaws. The coupling member includes drive pins that cooperate with the cam slots whereby squeezing of the actuating mechanism first effects pivotal rotation of the pair of forceps jaws over a first range of motion of the actuating member and translation without rotation of the forceps jaws over a second range of motion of the actuating member.

A surgical stapler has a handle assembly including a stationary handle and a trigger. The stapler also has a drive assembly with a body having a working end and a cam member supported on the working end. The cam member is positioned to translate relative to the anvil to maintain the anvil in the closed position during firing of the stapler. The trigger is operatively connected to a power cell. The power cell is operably connected to a motor of the drive assembly. The manipulation of the trigger actuates the power cell such that the power cell powers the drive assembly to effect translation of the cam member relative to the anvil. The stapler also has a channel for supporting the staple cartridge and the motor of the drive assembly controls the actuation sled supported within the cartridge. The actuation sled urges the plurality of staples from the cartridge when the anvil is in the closed position and in cooperative alignment with the staple cartridge.

The Customer Activated Multi-Value (CAM) card provides a customer with a primary use as a transaction card which can be further activated to have a secondary use as a credit card. The CAM card can be activated as a transaction card or as a transaction card with a credit card feature. Activation of the CAM card as a transaction card allows the customer to purchase goods and services from one specific vendor and to establish a relationship with that vendor for the goods or services rendered (for example, telephone calling card or gasoline product purchasing card) while enjoying reward benefits based on those purchases. Activation of the credit feature of the card allows the customer to interact with any merchant that accepts traditional credit cards such as VISA®, MASTERCARD®, AMERICAN EXPRESS®, or DISCOVER®. The combination of features allows a customer to purchase various goods and services from several different merchants. If the customer chooses to activate the CAM card as both a transaction card and a credit card, the customer is given the benefit of using the card in both manners described above.

A cam-actuated connection device joins rail mounting members of a photovoltaic panel array. The connection device slides within channels of mounting members until the members are in a properly positioned grid. When in position, the connection device is rotated to lock the mounting members in a rigid grid network. The connecting device can be subsequently loosened, repositioned and locked into position. The rail-mounting members create a grid for installation of multiple PV panels. The mounting rail allows the unit to remain relatively compact in nature but still covers a wide range of PV panel thicknesses. The rail system has a hinged connection with the mounting rail that allows an installer to assemble the module in a near perpendicular fashion to the mounting rail, make the required electrical connections and then lower the PV module into its working position. The unit is then locked into its working position.

A spinal fixation system is provided that, in one form, includes a coupling member having a cam lock member that is fixed against translation as it is turned with turning of the cam lock member causing an elongate member such as a spinal rod to be pushed downward in the coupling member for fixing the rod therein. In another aspect, the rod is fixed against a low profile insert that seats in a recess formed in the head of an anchor member projecting from the coupling member. The insert has an upper surface against which the rod is fixed. In one form, the insert upper surface is flat to provide for line contact against the rod so as to minimize damage thereto. In another form, the cam lock member cams against a clamping member driving it downward in the coupling member for fixing the rod therein.

An apparatus for supporting a load is disclosed. A support arm in accordance with an exemplary embodiment of present invention comprises a first strut, a second strut, a proximal link, and a distal link. A proximal portion of the first strut is pivotally coupled to the proximal link at a first proximal joint. Additionally, a proximal portion of the second strut is pivotally coupled to the proximal link at a second proximal joint. A distal end of the second strut is pivotally coupled to the distal link at a second distal joint. A distal end of the first strut is pivotally coupled to the distal link at a first distal joint. The support arm also includes a cam mechanism comprising a cam and a cam follower.

A content distribution system and method which prevents unauthorized access to secured content such as movies and music. The apparatus includes a source, a receiver, an authorized security device such as a conditional access module (CAM) for decrypting authorized content, an output device for outputting content and a backend for managing accounts and system operations. One aspect of this invention provides a mechanism for providing secured content on a medium such as a DVD optical disc. These devices may verify that there is authorization to play the secured content, add watermarks to the secured content, convert the secured content to a displayable form and provide a means for preventing output of the secured content.

A panel locking and regulating device of a drawer with a dump rail comprises the dump rail which is connected with the drawer; a panel of the drawer is connected with a regulating seat by a connecting piece, the regulating seat is internally provided with a conduit ferrule, in which the connecting piece can slide. The conduit ferrule is internally provided with a panel locking mechanism which includes an offset cam, one end of which is articulated on the regulating seat and the other end is articulated with a guide block by a connecting rod; one end of a swing rod is articulated on the guide block by a pin roll; a torsion spring is sheathed on the pin roll, and one end of the torsion spring leans against the swing rod and the other end leans against the guide block or the regulating seat; a sliding bush of the guide block is positioned in the regulating seat and the end part of the connecting piece is connected with the other end of the swing rod. The sliding bush of the guide block is positioned in a location bracket, and the rear part of the guide block is connected with one end of a first spring and the other end of the first spring leans against the location bracket. The invention has the advantages of simple and reasonable structure, flexible operation, high safety, which not only can realize the up and down regulation of the position, but also can realize the left and the right regulation of the position, and the panel can also be separately assembled and disassembled.
