An identification system comprising a plurality of differently frequency coded markings including mechanical vibrating means, and a detector device for detecting the frequency or combination of frequencies of the vibrating means. The vibrating means of the various markings are preferably made from identical comb-like members having teeth which are vibratory with different natural frequencies and of the type used in small music boxes. The different frequency codes may then be obtained by removing teeth in different combinations from the members used in the various markings. The markings may, for example, be arranged on dairy cattle, and the identification system may then be used in connection with a milk sampling system.
The present invention discloses an IC card, and a processing device for the IC card and a processing method therefor. The IC card comprises a semiconductor IC in which a large number of data are stored. There are provided a winding which picks up an electromagnetic field for forming a power current with respect to the semiconductor IC, and another winding and a Hall element for picking up the data of the semiconductor IC or writing the data into the semiconductor IC. These semiconductor IC, windings and the Hall element are all assembled within a card member of plastics. A device for processing this card comprises a winding for forming an electromagnetic field as a source of power current, another winding and a Hall element for transmitting data to the IC card and receiving it therefrom, and a circuit cooperative with these windings and the Hall element. These IC card and the processing device electromagnetically effects transmission of power current and data in accordance with so called a non-contact system.
A holder for an electronic detection element, which is adapted for attachment about the neck or other part of the body of an animal to be detected by a band. The holder is provided with a cavity for receiving the detection element and with at least one clamping member for adjustably clamping a band end.
Siping, of a specific pattern, is used as a code to provide an identification number and/or a part number on a rubber object. The depth and width of the sipes, and the height and width of the rubber bars between the sipes, can be read using a zero contrast reading device, and the specific pattern of sipes and bars can be converted into identifying symbols such as letters and/or numbers. The identity of the object can be matched with a data base which may provide the history of the object.
A process and apparatus are disclosed for taking a representative milk sample during the delivery of a milk charge from one container to another. With respect to the errors encountered in operating peristaltic pumps with different speeds of revolution, the invention predetermines a corrected pumping characteristic as a function of an acceptance characteristic and correspondingly controls the taking of samples.
A system and ingestible boluses for monitoring physiological parameters of animals. The boluses include circuitry for storing a selectable identification code, for sensing a physiological parameter, and for transmitting a data burst signal which includes information corresponding to the identification code and a sensed physiological parameter. In addition to the boluses, the system includes a receiver for receiving data burst signals transmitted from the boluses. According to one mode of operation, the bolus transmits data burst continuously at a preselected rate. The receiver can be coupled to a processor which can process data from the data burst signals.
