Abstract: A pressure sensitive pad configured to be placed under a mattress and configured to identify presence and absence of a threshold weight on the mattress. The pressure sensitive pad comprises a signal generator, a sensing zone, at least one variable matching resistor, a microcontroller unit (MCU). The signal generator configured to generate an electrical signal. The sensing zone has a sensing resistor with a first resistance which varies depending on a pressure applied on sensing zone. The variable matching resistor is in series with the sensing resistor and the signal generator, the variable matching resistor having a second resistance. The MCU has an analog-to-digital converter (ADC) configured for receiving and measuring a portion of the signal at an electrical junction between the sensing resistor an the at least one variable matching resistor, the MCU being configured to control the second resistance of the at least one variable matching resistor.

Abstract: A patient position pad is provided that includes a timer. The patient position pad is configured to detect the position of a patient. The timer is configured to track the useful life of the patient position pad.

Abstract: The invention provides systems and methods for a acquiring, manipulating, and monitoring data associated with one or more assisted living facilities. The invention includes utilizing one or more monitoring devices to gather data regarding at least one assisted living facility. The data is then transmitted across a network and saved in a database. An enterprise management application then operates on the data to manipulate and display the data according to parameters and instructions specified by one or more users. The data may be used by the one or more users to monitor and manage the one or more assisted living facilities.

Abstract: A system provides electrical power and compressed air includes a wheeled hand truck frame, an engine, a compressor, a generator, and a reservoir having several horizontally disposed cylindrical tanks in fluid communication and arranged in one or a few vertical planes. A portion of a lower-most tank of the reservoir is below the plane including the axle for the wheels; and the respective centers of gravity of the engine, the fuel tank, and the reservoir are arranged for relatively greater stability. A control system for the engine, generator, and compressor provides priority response to air demand and/or priority response to electrical power demand by reducing lower priority loads on the engine prior to increasing engine speed. A throttle controller moves the engine throttle from high speed to low speed in response to low demand for compressed air in combination with low demand for electrical power. The throttle controller includes a low demand valve and throttle positioning air cylinder.
