The DC-to-DC converter controller is configured to generate the phase control signals in a manner which (a) balances magnitude of current processed among the two phases of each power stage and (b) balances magnitude of current processed among the plurality of power stages.

Abstract: A switching power converter includes an integrated transformer and coupled inductor, first and second primary switching circuits, and a master controller. The integrated transformer and coupled inductor includes (a) first and second primary windings electrically coupled in series and (b) first and second secondary windings. The first and second primary switching circuits are electrically coupled to an end of the first primary winding and an end of the second primary winding, respectively. The master controller is configured to determine a magnitude of magnetizing current of the integrated transformer and coupled inductor from a difference between magnitude of current flowing through the first secondary winding and magnitude of current flowing through the second secondary winding, when the first and second primary switching circuits are in their respective off-states.

Abstract: A media slice includes a guide member and a docking surface with locating members, locking members and a first connector. A cavity in the media slice is open to the docking surface. An information handling system includes locating member receivers and a second connector. The information handling system is docked in the media slice by using the guide member and locating members to align the information handling system above the media slice. The locating members engage the locating member receivers and hold the information handling system parallel to the docking surface. With the locating members and locating member receivers engaged, the information handling system may be lowered onto the media slice, allowing the first connector and second connector to be mated and the locking members to lock the information handling system to the media slice. A battery may be stored in the cavity to be locked into the information handling system/media slice combination.

Abstract: An apparatus and method for holding dental laminates is provided. A sheet is provided with an attachment means running along the center of the sheet that attaches the dental laminates to the sheet. The sheet may be stacked on top of several other similar sheets to form a pad. The pad is placed onto a platform such as a base, and inserted into an opaque box that blocks out the light so the light sensitive resin placed on the dental laminates does not cure until the dentist is ready to place the dental laminates onto a patient's teeth. The dental laminates can be held in the box until the dentist is ready to place the dental laminates onto a patient's teeth.

Abstract: A computer system includes a portable computer having a base portion and a lid portion connected to pivotally open relative to the base portion. A heat generating component is mounted in the base portion. A first heat transfer system is mounted in the base portion adjacent the heat generating component. A second heat transfer system is mounted in the lid portion. A thermal hinge pivotally interconnects the first heat transfer system with the second heat transfer system, so that heat is dissipated from the base portion to the lid portion. A fan mounted in the lid portion actively dissipates heat from the lid portion.

Abstract: A patella planer for preparing a resected surface on a patella in a single operation. The patella planer has an adjustable stop which can be used on either side of the planer so that the planer may be used on the right or left knee. The adjustable stop has a floating zero pointer which can be set to accommodate varying thickness of the patient's patella. The amount of patella material to be removed can be selected by adjusting an offset stop pin.

The guidewire takes the form of a coiled wire which is coated with copolymers of methylsiloxane and aminoalkylsiloxane units to enhance the lubricity of the guidewire when it is inserted into a catheter.

Abstract: An endocardial lead which includes an elongated, flexible, insulative tubing, a central flexible conductor positioned within the tubing and having one end adapted to be electrically connected to a pulse generator. A ribbon-shaped bonding member is connected to the other end of the central conductor.

A drive mechanism in the form of a helical metal ribbon is received within the sheath, extends from the proximal end of the lead to the distal end of the lead, is fixed to the other end of the mounting member and defines a lumen through and in which a stylet can be received.

Abstract: A termination for a carbon fiber implantable lead. A terminal assembly includes a hollow terminal member having lateral ports through which carbon fiber bundles pass. Exposed tips of the carbon fiber bundles are folded back and held against the exterior surface of the terminal member by a housing member. The housing member frictionally engages the exposed fiber tips. A stylet entry guide member is frictionally engaged with the interior of the end of the terminal member. One end of the guide member is coupled to a stylet tube which passes through the terminal member and the lead. This configuration provides a good electrical coupling between the terminal member and the carbon fiber bundles, as well as provides an axial passage through which a stylet may be inserted.
