A motion detector includes a microwave-based module to detect movement. Intermediate processing circuitry is coupled to an output from the module. The processing circuitry is activated intermittently to produce first and second pulsed output signals. Cross-correlation circuitry processes the two signals to produce a motion indicating output signal.

In one example, a shell includes walls that collectively define an interior space of the shell, the interior space sized and configured to receive heat generating equipment. An internal heat exchanger disposed within the interior space is arranged for thermal communication with heat generating equipment when heat generating equipment is located in the interior space. Additionally, an external heat exchanger is located outside of the shell and arranged for fluid communication with the internal heat exchanger. Finally, a prime mover is provided that is in fluid communication with the internal heat exchanger and the external heat exchanger, and the prime mover is operable to circulate a flow of coolant through the internal heat exchanger and the external heat exchanger.

A method, digital tool, device, and system for detecting movements of objects and/or living beings in a radio range, which enables easily with a minimum of hardware complexity an automated movement detection based on a Single-Sensor, is provided. The method includes collecting as input data for the movement detection based on received radio signals of an intended or unintended communication between a transmitting radio terminal being mobile or fixed and a receiving local fixed radio device in the radio range “Received Signal Strength”-values related quantities, determining a change in the received radio signals, which are derived from the facts that the movement influences the transmitted radio signal in the radio range based on the RSS-values related quantities by the indication of a statistical parameter value, and assessing the statistical parameter value until the statistical parameter value in accordance with a threshold check provides a reliable statement for controlling purposes.

In one example, a portion of a shell includes a shell wall portion that has an interior wall portion and an exterior wall portion located near the interior wall portion. In addition, fluid passageways are disposed between the interior wall portion and the exterior wall portion. One or more of the fluid passageways are defined in part by one or both of the interior wall portion and the exterior wall portion. The fluid passageways form part of heat exchanger that is integrated in the shell.

A method and system for detecting an intruder is provided. The method includes monitoring received signal strength in a wireless router and creating a profile of the received signal strength as monitored during a learn mode. The method includes comparing activity of the received signal strength in the wireless router, during an intruder detection mode, to the profile and issuing a notification, based on the comparing, wherein at least one step of the method is performed by a processor.

A sensor package is disclosed that includes, a compass, an accelerometer, and an electromagnetic flux tag based open/close sensor. The compass may be activated by a microcontroller in response to an indication of movement detected by an accelerometer. The compass's data may be utilized to determine an orientation for the object such as a door on which the sensor package is situated. The orientation data may indicate that the door is ajar and/or that a second magnetic field is present, suggesting tampering. A notice may be dispatched to a controller for the home security system, a client device, a remote system, etc.

Provided is a safety scanner capable of easily grasping the correspondence relationship between a distance measurement position on a scanning plane and a real space. The safety scanner includes a distance measurement section that obtains distance measurement information corresponding to a distance optically sensed and a scanning angle of a detection light, an intrusion sensing section that senses an intruder within the protection area on the basis of the distance measurement information and a area designation information, a marker identification section that identifies a marker movably disposed within the detection area, and the distance measurement information of the marker as an area generation information for determining the protection area.
