    摘要： A rate smoothing function used in implantable pulse generators uses detected triggering events, which cause the rate smoothing function to be activated or deactivated, and detected parameter adjusting events, which cause parameter(s) of the rate smoothing function to be changed. In one example, the activation/deactivation and/or change to the parameters of the rate smoothing function are temporary, and the pre-event state of the rate smoothing function is set to a post-adjusting state, such as after a first time interval. Rate smoothing may be selected, activated or deactivated, or adjusted based on a cardiac signal state, or based on an activity or other physiological sensor signal. The adjusted rate smoothing parameters may include an up-smoothing percentage to limit a speed of pacing rate increase and a down-smoothing percentage to limit a speed of pacing rate drop.

    摘要： Various approaches for activating a traffic control preemption system. A light bar includes a support structure and a plurality of LED modules individually mounted on the support structure. Each LED module includes a plurality of LED groups, and in at least one of the plurality of LED modules, at least one LED group in the module is an infrared (IR) LED group, and at least one LED group in the module is a visible light LED group. A controller is coupled to each module. The controller is configured to trigger an IR light pulse pattern at a first level of IR radiant power from the at least one IR LED group. The pulse pattern and first level of IR radiant power activate preemption in a traffic control preemption system.

    摘要： Various approaches for a traffic control preemption system that includes a receiver, a light emitter, and control circuitry. The receiver includes a photodetector and circuitry that produces a number of electrical pulses in response to each detected light pulse. For each detected light pulse the number of electrical pulses represents a level of radiant power of the light pulse, and a threshold number of electrical pulses and an activation frequency at which the threshold number of electrical pulses is repeated activates preemption. The control circuitry is coupled to the light emitter and controls the light emitter to emit bursts of light pulses. Each burst includes at least two light pulses and a frequency of light pulses in each burst and a frequency of the bursts cause the receiver to produce at least the threshold number of electrical pulses at the activation frequency and activate the preemption.
