Abstract: The present invention provides apparatuses and systems for adjusting a communication channel between a control unit and a remote sensor. A system may include a control unit that controls an environmental unit and a remote sensor that provides data about an environmental factor as measured at the remote sensor. The remote sensor transmits a radio frequency (RF) signal that conveys the data to control unit through a directional antenna. The RF signal is received by the control unit through an omnidirectional antenna, and a signal strength parameter is determined from the received RF signal. A signal strength indication unit provides an indication from the signal strength parameter as a user adjusts the position of the directional antenna. With embodiments of the invention, a signal strength module generates an audio signal in accordance with an audio characteristic, which is indicative of the signal strength of the received RF signal.

Abstract: A technique for quickly determining the type of liquid in a container externally regardless of the material of the container, preferably contactlessly. A halogen heater 102 and an infrared thermopile 103 are disposed outside an electrically conductive container 101 made of aluminum, for example. The surface temperature of the container 101 is measured when the halogen heater 102 is off, followed by the turning-on of the halogen heater 102 for two seconds, for example. The surface temperature of the container 101 is then measured, and a difference from the previous result of measurement is calculated. If the difference is smaller than a threshold value, the liquid in the container is determined to be a safe liquid consisting primarily of water, and a blue lamp is activated. If the difference is greater than the threshold value, the liquid in the container cannot be determined to be a safe liquid consisting primarily of water, and a red lamp is activated, indicating abnormality.
Abstract: Two sensor units are mounted on opposite sides of a transom of a boat and directed to a common location behind the boat. The field of view of the two sensors overlaps behind the marine propulsion unit of the boat to detect the presence of a heat emitting object, such as a mammal.

Signals from four infrared sensing elements are received by a controller which reacts, with an alarm signal, when at least two of the four sensors detect a heat emitting object within their individual fields of view. False triggering can be reduced by not providing an alarm signal if only the two most inboard sensors detect the heat emitting object.
