Abstract: An Example tool for implanting a pacemaker lead includes a body that includes a recess, a first electrical contact positioned within the recess, and a projection coupled to the body. In addition, the tool includes a second electrical contact positioned on the projection. The recess is configured to receive the pacemaker lead therein such that a first electrode of the pacemaker lead is to engage with the first electrical contact and a second electrode of the pacemaker lead is to engage with the second electrical contact. A rotation of the tool about a central axis of the pacemaker lead is configured to rotate the first electrical contact and the first electrode together about the central axis and to slidingly engage the second electrical contact along the second electrode.

Abstract: An unmanned aerial vehicle can be configured to adjust a beam direction, provide path information, act as a base station, act as a cluster head, include an improved directional antenna or array of directional antennas, communicate in a collaboration using belief propagation, receive communications from a serving station aiding in navigation or improved signal performance, or the like.

Abstract: A computer-implemented technique is described herein for receiving activity signals from plural logic components running on one or more computing devices. Each activity signal includes an activity information item (AII) that describes an activity performed by a subject (e.g., a user), or to be performed by the subject, as recorded by a logic component. The technique stores AIIs extracted from the activity signals in a graph data structure. The technique then: determines, by interrogating the graph data structure, one or more activity clusters within a span of time, each activity cluster pertaining to a group of AIIs associated with a same encompassing project; generates one or more summary documents based on the identified activity cluster(s); and sends the summary documents to an output device.

Abstract: A variable air volume ceiling diffuser includes a damper that is raised and lowered by a linkage that is controlled by a duct temperature sensor/actuator and one or more room temperature sensors/actuators. The linkage includes a heating slide movable for the heating mode and a cooling slide movable for the cooling mode. The duct temperature sensor/actuator selects the heating slide for movement by the room temperature sensors/actuators in the heating mode and selects the cooling slide for movement by the room temperature sensors/actuators in the cooling mode. The differential movement between the heating and cooling slides moves a roller that engages a profiled cam surface attached to two lever arms. As the roller moves along the cam surface, the lever arms pivot about their axis of rotation so that the damper moves upward to close the air inlet and downward to open the air inlet.
