Abstract: A liquid level sensor comprises a main body, a common electrical contact, a base-level electrical contact, and a first-raised-level electrical contact. The common electrical contact and the base-level electrical contact together define a base liquid sensing level. The common electrical contact and the first-raised-level electrical contact together define a first raised liquid sensing level. Electronic circuitry is responsive to a path between the common electrical contact and the base-level electrical contact being electrically closed by moisture to generate a base-level alarm signal, and responsive to a path between the common electrical contact and the first-raised-level electrical contact being electrically closed by moisture to generate a second-level alarm signal. Alternatively, a first pair of electrical contacts and a second pair of electrical contacts may be used.

Abstract: Embodiments provide an apparatus, a vehicle, a method, and a computer program for setting a transmission power. The apparatus (10) is operable to set a transmission power of a vehicular relay transceiver (100) in a mobile communication system (400). The relay transceiver (100) is operable in a vehicle (500) to relay information between a mobile transceiver (200) associated with the relay transceiver (100) and a base station transceiver (300) of the mobile communication system (400). The apparatus (10) comprises a transceiver module (12) which is operable to transmit a common signal using a transmission power. The transmission power influences a coverage area of the relay transceiver (100). The relay apparatus (10) further comprises a controller module (14) operable to determine information related to a quality of a radio link between the relay transceiver (100) and the base station transceiver (300) and information on a state of the vehicle (500).

Abstract: A optical system carried by a flying object such as a satellite or aircraft having a pair of optical paths having different Q values for obtaining a pair of images of the same spot on the Earth's (or other celestial body's) surface. The optical paths may have a portion in common with each other and a portion not in common with each other. Light is directed into the optical paths via a field sharing arrangement. One of the optical paths together with an imaging device creates relatively narrower field of view images with a higher ground resolution than the other optical path together with an imaging device.

Abstract: A magnetic detector locates magnetically tagged items, such as surgical sponges or instruments, introduced to and remaining in the body cavity of a surgical patient. The magnetic detector is a wand or probe that is manually handleable, and spatially manipulable and moveable, by an operator, such as a medical professional. The detector is moved about at a spatial location of an ambient magnetic field at the patient and operating table. A characteristic of the ambient magnetic field at the spatial location is saved by the detector. The detector is subsequently moved about at the same spatial location. If any magnetically tagged item is present in the vicinity of the detector during this subsequent movement at the spatial location, an anomalous magnetic effect is detected by comparison of the prior detection reading absent the tagged item to the detection reading in presence of the tagged item in the patient.
