A device for pulsing the control lines of an HVAC system in order for a user to discover which outside unit is associated with a particular inside unit. Lead wires from the device connect to the control contacts on the thermostat of an HVAC unit. The device is an electrical or electromechanical circuit that can use the power contained within the thermostat or can be battery powered. Once the device is connected, it pulses the control line for the reversing valve, in the case of a heat pump system, or pulses the control line for the compressor, for a cooling-only system. This pulsing creates a loud clicking sound in either case that allows the repair technician to decipher the correct outside unit corresponding to the inside unit without use of a helper.

This watching system is provided with: a watching detection device that is provided with a cartilage conduction vibration source, a mastication sensor, and a bone conduction microphone and that is configured to be mounted on an ear such that the entry of the ear canal is opened; and a mobile phone or an in-home monitoring unit that receives watching detection signals from the mastication sensor and the bone conduction microphone by means of short-range communication and issues a notification to the outside. The watching detection device has an air conduction microphone and also functions as a hearing aid. When detection signals cannot be received from the mastication sensor or the bone conduction microphone for a predetermined time period, a notification is issued. The mobile phone and the in-home monitoring unit crosscheck watching detection information. The mobile phone also issues a notification of information indicating that there is no abnormality.

A doorbell including a housing and mount that can be engaged such that the housing is pivotable or otherwise movable relative to the mount for engagement with the mount and/or for activation of a doorbell switch. A latch can secure the housing to the mount so the housing is secured to the mount. A switch located in a space defined by the housing and mount can be actuated based on movement of the housing relative to the mount.

There is provided a device for monitoring the use of a blister package, strip package, vial or bottle contents at a distance. A processor is connected to a compact random or quasi-random n-microphone array and is programmed to detect the sound of the content being expelled from a blister cavity, strip package, or a cap being removed from a vial or bottle. A content use data memory associated with the processor stores information relating to the expulsion or removal events. The processor is equipped with statistical means for differentiating the sound of the content being expelled, from the background noise, generating an electrical signal that is analyzed for relevance to content use events by the processor, and storing the resulting use data in memory. The processor may have an adaptive beam focussing algorithm to determine the direction of the source of the sound.
