Abstract
Among other things, a system for lighting a light for an individual rising from a bed is provided. In particular embodiments, the system can include a mat and a light unit wirelessly connected, so that when an individual steps on the mat as he or she rises from the bed a signal is sent to the light unit, activating the light. A weight sensor in the mat can measure the weight placed on the mat, so that unintentional lighting can be avoided and so that weight information can be recorded. Embodiments can also include a signal transmitter to send weight and activation information to a remote receiver.
Claims11
A wireless night light system for turning on a light remote from an individual in a bed, comprising:
- a light unit having a wireless receiver, a power source, an electrical connection for transferring power from the power source to the light, and an electronically-operable switch;
- a mat for placement on a floor adjacent a bed, the mat having a pair of metallized polyester layers separated by a compressible partition and connected to an inductance to form an LC circuit having an oscillation frequency dependent on the distance between the metallized polyester layers, said partition having an uncompressed thickness which corresponds to an uncompressed oscillation frequency value;
- a microcomputer electronically connected to and adapted to monitor the oscillation frequency of the LC circuit, said microcomputer programmed to compare the oscillation frequency to the uncompressed oscillation frequency value, and to determine a weight applied to the mat from the oscillation frequency;
- a first wireless transmitter for transmission of a first signal adapted for reception by the wireless receiver of the light unit, the first wireless transmitter controlled by the microcomputer;
- a second wireless transmitter for transmission of a second signal adapted for reception by a remote receiver, the second signal including information including the value of the weight, the second wireless transmitter controlled by the microcomputer;
- wherein the microcomputer instructs the first and second wireless transmitters to transmit the first and second signals on determining that the oscillation frequency differs from the uncompressed oscillation frequency value by a predetermined amount, and wherein on receiving the first signal the switch of the light unit allows power to the light, lighting the light.
A wireless night light system for turning on a light remote from an individual in a bed, comprising:
- a light unit having a wireless receiver, a power source, an electrical connection for transferring power from the power source to the light, and an electronically-operable switch;
- a mat for placement on a floor adjacent a bed, the mat having a weight sensor for measuring weight values of weight applied to the mat and electronically connected to a microcomputer, a first wireless transmitter controlled by the microcomputer for transmission of a first signal adapted for reception by the wireless receiver of the light unit, a second wireless transmitter controlled by the microcomputer for transmission of a second signal adapted for reception by a remote receiver, the second signal including information including the value of the weight, and a plurality of light-emitting diodes fixed to the mat and controlled by the microcomputer;
- wherein the microcomputer is programmed with an initial weight value and is adapted to compare weight values received from the weight sensor with the initial weight value, and to instruct the first and second wireless transmitters to transmit the first and second signals on determining that a received weight value exceeds the initial weight value, and wherein on receiving the first signal the switch of the light unit allows power to the light, lighting the light.
