Abstract: Systems and methods for improving power usage of a wireless device are disclosed. The wireless device includes a memory; and at least one processor communicatively coupled to the memory, the at least one processor configured to: determine a change in ambient light received by the wireless device; determine a position of the wireless device; activate a low power image sensor based on at least one of the change in the ambient light or the position of the wireless device; detect a face using the low power image sensor; and turn on a display of the wireless device based on a user face being the face detected.

Abstract: A method for performing a demand analysis for a hospital, including: (i) receiving hospital capacity information; (ii) receiving hospital data, the hospital data comprising information on patient admissions, patient discharges, and patient transfers for a previous period of time for each of a plurality of patient types; (iii) adapting parameters of a machine learning algorithm based on the hospital data; (iv) receiving clinical information about patients currently admitted in the hospital; and (v) determining, based on output from the adapted machine learning algorithm and using the current clinical information and the hospital capacity information, a predicted patient flow for the hospital in real-time. The method further includes displaying, to at least one user in real-time, the predicted patient flow for the ward and at least one suggested rearrangement of resources within the hospital.
