Patent number: 7354195Abstract: A temperature measuring device and a temperature measuring method are provided which are capable of obtaining precise measured temperature values with respect even to old persons, sucklings or infants, which device may be formed into a disposable type according to need, which method may be carried out using such a disposable type device according to need, and which enable precise temperature measurement in real time. An on-subject temperature measuring device 1, which is attached to a subject when a temperature of the subject is measured, receives a radio wave from a reader 2 as an external device and is thereby electrically powered. Using the electric power, temperature measurement is performed in the on-subject temperature measuring device 1. The results of the measurement are transmitted through radio waves to the reader 2 in the form of a temperature of the subject and ID data.Type: GrantFiled: March 20, 2003Date of Patent: April 8, 2008Assignees: Zixsys Inc., FEC Inc.Inventor: Motoya Sakano

Patent number: 7265682Abstract: Methods and systems employing combined source-channel coding for multi-carrier modulation (MCM). In some embodiments, a described method comprises: estimating channel gain to noise ratio (CGNR) as a function of frequency bin; determining MCM parameters that minimize distortion of one or more telemetry signals; generating a communications signal using the MCM parameters, and transmitting the communications signal via a communications channel. The MCM parameters may be determined by minimizing a telemetry signal distortion measure subject to CGNR and a transmit power constraint. The MCM parameters may further account for differing fidelity requirements when multiple telemetry signals are being transmitted.Type: GrantFiled: March 29, 2005Date of Patent: September 4, 2007Assignee: Halliburton Energy Services, Inc.Inventors: Mahsa Memarzadeh, Wallace R.
