The disclosure relates to a drug delivery device, comprising a mechanical audible indicator capable of producing an audible signal with a volume of at least 100 dB.

A portable panic alarm assembly includes a housing and an audible alarm device mounted within the housing. The alarm device is electrically and operably interconnected between first and second alarm contacts. A battery mounted within the housing has a pair of oppositely charged electrodes. A first electrode is connected to the first alarm contact. An actuator switch is slidably mounted in the housing and includes an actuator contact. The actuator switch is operably alternated between an open state, wherein the second battery electrode is disconnected from the second alarm contact to deactivate the alarm and a closed state, wherein the second battery electrode is connected to the second alarm contact to activate and sound the alarm.

The invention relates to a cooking vessel (1) comprising a cap (2) equipped with an end wall (3). According to the invention, the end wall (3) comprises a housing (6) accomodating at least one bimetallic element (30a, 30b) that adopts a cold stable first position when the temperature is below a predetermined temperature and toggles into a hot stable second position when the temperature is above the predetermined temperature, and vice versa, the transition from the first stable position to the second stable position generating an audible signal designed to be perceived by a user or by an external device.

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.

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.
