Abstract: The present disclosure relates to aggregating and sharing wellness data. The wellness data can be received by a user device from any number of sensors external or internal to the user device, from a user manually entering the wellness data, or from other users or entities. The user device can securely store the wellness data on the user device and transmit the wellness data to be stored on a remote database. A user of the device can share some or all of the wellness data with friends, relatives, caregivers, healthcare providers, or the like. The user device can further display a user's wellness data in an aggregated view of different types of wellness data. Wellness data of other users can also be viewed if authorizations from those users have been received.

Abstract: An imaging and asynchronous laser pulse detector (ALPD) device, imaging cell of the imaging and ALPD device and method of use is disclosed. A detector generates an electrical signal in response to receiving an optical signal, wherein a frequency of the electrical signal is indicative of a frequency of the optical signal. A first detection/readout circuit is sensitive to a first frequency range, and a second detection/readout circuit is sensitive to a second frequency range. The first detection/readout circuit allows the electrical signal to pass from the first detection/readout circuit to the second detection/readout circuit.

Abstract: A focal plane array includes a mosaic integrated circuit device having a plurality of discrete integrated circuit tiles mounted on a motherboard. The focal plane array includes an optically continuous detector array electrically connected to the mosaic integrated circuit device with an interposer disposed therebetween. The interposer is configured to adjust a pitch of the continuous detector array to match a pitch of each of the plurality of discrete integrated circuit tiles so that the optical gaps between each of the plurality of integrated circuit tiles on the motherboard are minimized and the detector array is optically continuous, having high yield over the large format focal plane array.

Abstract: A digital pixel includes a capacitive transimpedance amplifier (CTIA) coupled to a photodiode that receives an electrical charge and output an integration voltage. An integration capacitor coupled to the CTIA accumulates the integration voltage over an integration period. A comparator compares the accumulated integration voltage with a threshold voltage and generates a control signal at a first level each time the accumulated integration voltage is greater than the threshold voltage. A charge subtraction circuit receives the control signal at the first level and discharges the accumulated integration voltage each time the control signal at the first level is received from the comparator. An analog or digital counter receives the control signal at the first level and adjusts a counter value each time the control signal is received from the comparator. An output interface communicates the counter value to an image processing circuit at an end of the integration period.
