A television (1) including a function of a call using Internet Protocol (IP) includes: a communicating section to transmit and receive a call signal over an IP communication network; an incoming call destination identifying section (11) to identify a user who is designated as an incoming call destination; a judging section to detect a person who is present around the television (1); and a communication control section (13) to transfer the call signal to a mobile phone (4) of the user in a case where a plurality of persons containing the user has been detected. This offers a television capable of a call and ensuring the privacy of the call.
摘要:
A control device that controls an electric motor drive device. The control device is configured with a first voltage control section that derives a modulation rate representing a ratio of an effective value of the voltage command values to the DC voltage and a voltage command phase. A second voltage control section generates a control signal for controlling the DC/AC conversion section on the basis of the modulation rate, the voltage command phase, and a magnetic pole position representing a rotational angle of a rotator of the AC electric motor. A computation cycle of the first voltage control section is set to be longer than a computation cycle of the second voltage control section.

An upper floor member 30 unitarily includes a floor panel portion 30a for forming a floor surface 12, a first wall portion 30b extending downwards from circumferential edges of the floor panel portion 30a and continuous in the circumferential direction, and a second wall portion 30c spanned between opposed portions of the first wall portion 30b and progressively increased in thickness toward the center of the floor panel portion 30a. The floor panel portion 30a is polygonal in shape, and the first wall portion 30b is progressively increased in thickness toward the center of each side. The first wall portion 30b extends downwards to the vicinity of the lower floor, and its lower end is supported by a support means 18. Thus, a double floor structure which is inexpensive, has a high stiffness, good workability, and offers a high vibration-damping performance can be provided.

摘要:
A linear regression equation is comprised of the objective variables and the explanatory variables. The objective variables are comprised of the L1 carrier phases, the L2 carrier phases, the C/A code pseudorange, the P(Y) code pseudorange, the clock error data, the delay data of the ionosphere, and the delay data of the troposphere that related with every satellite respectively. The explanatory variables are comprised of at least the integer ambiguity and a receiver's position.The receiver's position has been linear-approximated by using the estimation results of the passed receiver's positions. Applying a least square method to the regression equation, the integer ambiguity and the receiver's position is estimated.
