Abstract: Devices, systems, and techniques are disclosed for verifying the occurrence of an acute health event. An example device includes communication circuitry configured to receive a communication indicative of an acute health event of a patient and memory communicatively coupled to the communication circuitry and being configured to store the indication of the acute health event. The device includes processing circuitry communicatively coupled to the communication circuitry and the memory. The processing circuitry is configured to, in response to the communication, verify the acute health event and based on the verification of the acute health event, send an alert regarding the acute health event.

Abstract: A programmable beam blocker includes a liquid crystal based grid of pixels, one or more groups of pixels, or plurality of pixels, corresponding to individual beams of light. The application of a voltage through one pixel can change the phase of the liquid crystal material to prevent the transmission of light through it.
