Abstract: Portable ECG monitoring apparatus comprises a sensor device 1 detachable from a monitoring device 2. The sensor device includes ECG sensors attached via cabling 5 to a connector 4. The sensor device 1 and monitoring device 2 are connected by attaching the connector 4 to the monitoring device 2, which provides a watertight seal for the apparatus and prevents access to any internal components in the monitoring device 2.

Abstract: ECG recording apparatus 1 includes a port 2 for connection to ECG electrodes and a microphone 3 for detecting vocal signals, Processing electronics store a recording of the vocal signals and the physiological data on the storage medium 4.

Abstract: A hob comprises a substantially planar member having apertures defining hotplate regions, a glass-ceramic insert being positioned in each aperture above a radiant heating element. The use of a molded glass insert corresponding to a hotplate region offers several advantages over prior art hobs conventionally comprising a glass-ceramic sheet formed by a flat glass process which extends over a plurality of hotplate regions. Another embodiment consists of a drop-in heating unit for a hob comprising a metal can, a substrate, a resilient annular spacer, a radiant heating element and a molded glass-ceramic insert. An over-temperature thermal limiter acts to prevent the unit becoming overheated. A metal compression band extends around a downwardly protruding skirt of the insert, increasing its resistance to shock.
