Abstract: A system and method of tracking physical activity of a person in order to help motivate that person to add more exercise to their lives. Each participant is provided a motion sensor that detects forces incurred by the participant. The motion sensor creates electronic data that corresponds to the forces detected. The data is analyzed to determine whether or not exercise has been performed. The analysis can also determine the type of exercise performed, when the exercise was performed, and the duration of the exercise performed.

Abstract: A tubular encasing netting for sausage and similar articles. The encasing netting contains a longitudinally running tear-open thread, the length of which is greater than that of the encasing netting in the state of use of the latter. This results in loops of the tear-open thread which are accessible from outside and which can be grasped for tearing open. The encasing netting is expediently a double-rib or warp-knit fabric. The tear-open thread is received in stitches of this fabric. The invention relates, furthermore, to a method for producing such an encasing netting, to a sausage casing connected to the encasing netting and to an article encased by this encasing netting.

Abstract: A tubular encasing netting (1) for sausage and similar articles. The encasing netting (1) contains a longitudinally running tear-open thread, the length of which is greater than that of the encasing netting (1) in the state of use of the latter. This results in loops (7) of the tear-open thread which are accessible from outside and which can be grasped for tearing open. The netting is expediently a double-rib or warp-knit fabric. The tear-open thread (3) is received in stitches of this fabric. The invention relates, furthermore, to a method for producing such a netting, to a sausage casing connected to the netting and to an article encased by this netting.

Abstract: Method for setting and/or checking the flow or through-flow in valves, particularly injection valves for internal combustion engines. The injection valve is placed in a measuring device and subject to the action of a fluid. The fluid is passed through the valve at a given volume flow. The pressure set in the measuring device is determined and serves as a measure for the setting and/or checking of the injection valve.

Abstract: A lens mount, especially but not exclusively for use with motion picture cameras, with special means for preventing transmission of noise through the lens mount from operation of moving parts within the camera to a microphone located in front of the camera. A focusing lens mount has two mounting parts which are movable axially relative to each other, and with a small clearance space between these two parts. An annular groove is provided, extending circumferentially around a cylindrical portion of one of these mounting parts. In this groove is a sound damping or impeding element, resiliently pressed against a companion cylindrical surface on the other of the mounting parts, to block passage of sound through the clearance space between the two cylindrical parts. The sound damping element is made of material having good dry-sliding characteristics.

Abstract: A focusing system for long focal length objectives, having an intermediate tube between the camera and the objective proper. For purposes of focusing, there is a displaceable part movable longitudinally through the intermediate tube, and movement of this part serves to move the lens elements axially for focusing. A receiver portion on the bottom of the intermediate tube receives interchangeably, in quickly attachable and detachable manner, either one of two different focusing mechanisms, the first having the shape of a gun stock with a trigger-like member serving to focus the lens quickly but not necessarily precisely when quick picture shooting of moving objects is desired, the second mechanism having means for accurate focusing and a tripod thread socket. Provision is made for turning the camera 90 degrees to change the format of the picture.

Abstract: Interchangeable lens assembly having a composite two part telescoping force transmission shaft, which functions as a cocking and releasing member, which has one end engageable with the cocking member of the shutter system and the other end engageable with a camera-side drive shaft when the lens assembly is attached to the camera, and which serves for the transmission of torques, i.e.
