Abstract: An identifying apparatus which can identify objects having electronic identification devices (EIDs). The identifying apparatus includes multiple EID readers positioned in a spaced apart relationship to define multiple pathways so that EIDs carried by the objects can pass in a single file through any one of the multiple pathways. Each EID reader is adapted to read any EID as the objects pass through any one of the pathways. Each EID carried by an object is recorded only once irrespective of the number of times an EID reader reads an EID.

Abstract: A security system including in combination a signal transmitter carried by an object wherein the signal transmitter is adapted to transmit a signal, a signal receiver adapted to receive signals, transmitted by the signal transmitter, a control unit adapted to process received signals and adapted to control an alarm system in accordance to the received signals, wherein the control unit in response to a processed received signal from the signal transmitter controls the alarm system such that the presence of objects with the signal transmitter in a designated area will not activate the alarm of the alarm system, however the control unit continues to allow the alarm of the alarm system to be activated if the alarm system senses objects without the signal transmitter in the designated area.

Abstract: An antenna system for use in processing of livestock carcasses including in combination, antenna means adapted to transmit and receive signals from transponders in or on carcasses moving on a conveyer system, support means adapted to support the antenna, pivoting means adapted to enable the antenna to pivot on the support means as each carcass comes into contact with the antenna, wherein in operation, the pivoting action enables a wiping contact to be maintained between the antenna and a carcass sufficient to obtain a positive reading of the transponder irrespective of a rotational and/or angular displacement of the carcass about a vertical axis without causing dislodgement of the carcass from the conveyer system or bruising of the carcass.

Abstract: An identification apparatus for animals or carcasses carrying electronic identification devices, (EID) (2) moving past an antenna (10). The identification apparatus including motion sensing means (12, 13, 14, 17) and marking means (16) adapted mark the animals or carcasses according to whether EID (2) is present, absent or non-functioning, whereby the animals' carcasses can be identified, drafted or sorted according to marking supplied.
