Abstract: Systems, devices, and techniques for establishing communication between two medical devices are described. In one example, an implantable medical device comprises communication circuitry, therapy delivery circuitry, and processing circuitry configured to initiate a communication window during which the implantable second medical device is capable of receiving the information related to a cardiac event detected by a first medical device, the communication window being one of a plurality of communication windows defined by a communication schedule that corresponds to a transmission schedule in which the first medical device is configured to transmit the information, control the communication circuitry to receive, from the first medical device, the information related to the cardiac event that is indicative of a timing of the cardiac event with respect to a timing of the communication window, schedule and control delivery of a therapy according to the information related to the cardiac event.

Abstract: A cover for concealing utility equipment on real property such as air conditioner condenser units, telephone and electric cabinets, and trash containers, has a modular, rigid and stiff skeletal frame and a filtration layer of fine mesh supported on the vertical faces of the skeletal frame. The cover includes artificial foliage in the form of sprigs that closely simulate the appearance of natural, leafed, shrubbery branches. The sprigs are affixed to substantially vertical rods positioned laterally across the face of the frame. The cover presents an aesthetically pleasing natural foliage appearance that substantially completely blocks the view of the concealed equipment. Lengths and angles between components of the cover and the number of components can be adjusted such that a single cover kit is alone or in combination with supplementary components adaptable to fit objects of different sizes and shapes.

Abstract: A cover for concealing utility equipment on real property such as air conditioner condenser units, telephone and electric cabinets, and trash containers, has a modular, rigid and stiff skeletal frame and a shell of flexible openwork material. The shell includes artificial foliage such that the cover appearance closely simulates natural plants and is aesthetically compatible with the local environment. Lengths and angles between components of the cover and the number of components can be adjusted such that a single cover kit is alone or in combination with supplementary components adaptable to fit objects of different sizes and shapes.

Abstract: The tracks of a tracked vehicle are subject to a tension control system which includes a movable idler wheel for applying force to each track, a hydraulic actuator for dynamically applying force to each track at a zero spring rate, a pilot controlled check valve for selectively locking the actuator against tension relieving return movement, and a control sensitive to vehicle steering, direction of movement, acceleration and deceleration for deciding according to a preset program whether each actuator should be locked or free to move. An operator controlled switch modifies system hydraulic pressure to permit an optional low pressure operation.
