Abstract:
There is provided a display control device, including a communication section for communicating with an external device, a position specification section for specifying positions of an imaging device, which captures an image, and a display device, which displays the image, a process determination section for determining whether to cause the captured image to be reversed in a horizontal direction on the basis of the positions of the display device and the imaging device and a processing section for selectively reversing the captured image in the horizontal direction, wherein the processing section causes the display device to display the image reversed in the horizontal direction by reversing the captured image in the horizontal direction, if the image is determined to be reversed in the horizontal direction, and causes the display device to display the captured image, if the image is determined not to be reversed in the horizontal direction.
Abstract:
An object of the present invention is to provide a decorative illumination signboard capable of effectively downwardly emitting light while suppressing an upward emission of light with a simple configuration and a plastic sheet used in the decorative illumination signboard.The object can be accomplished by a plastic sheet having optical transparency which includes an exit surface and an incident surface on which a plurality of prism lines having a flat and smooth surface are arranged to be aligned. A shape of the prism in a cross-section perpendicular to a longitudinal direction of the prism line is formed by a side A on a lower side at an angle of α degrees to a normal line of the exit surface and a side B on an upper side at an angle of β degrees to the normal line of the exit surface and α
Abstract:
A wireless communication device includes: a data transmission unit that transmits data to one or more receiving terminals; and a communication mode determination unit that determines a communication mode in which the data is transmitted from the data transmission unit, wherein the communication mode determination unit selects a first communication mode in which unicast communication is used when the number of receiving terminals to which the data is transmitted is equal to or less than a predetermined number, and selects a second communication mode in which unicast communication is performed to one or some of receiving terminals as a destination and the other receiving terminals than the destination also receive packets in unicast communication when the number of receiving terminals to which the data is transmitted exceeds the predetermined number.
Abstract:
A wireless communication apparatus includes a transmitting portion to transmit a data signal to other wireless communication apparatus, a receiving portion to receive a reception confirmation signal indicating reception of the data signal by the other wireless communication apparatus from the other wireless communication apparatus during a specified period, a determination portion to determine that a predetermined requirement is satisfied if the receiving portion receives a given signal during the specified period, and a control portion to control the transmitting portion to request the other wireless communication apparatus to retransmit the reception confirmation signal if the receiving portion does not normally receive the reception confirmation signal and the determination portion determines that the predetermined requirement is satisfied.
Abstract:
A wireless communication apparatus having a wireless communication function capable of using a plurality of transmission rates. The wireless communication apparatus includes utilization-factor calculation means for calculating a utilization factor of a wireless transmission path through which wireless communication is performed using the wireless communication function; and determination means for determining a transmission rate at least on the basis of the utilization factor calculated by the utilization-factor calculation means.

Abstract:
A portable terminal monitors a signal level of a short-range wireless signal from a wireless communication apparatus. If the signal level drops so low that a state of connection for short-range wireless communications cannot be maintained between the two apparatuses, use of predetermined functions of the portable terminal is limited. A short-range wireless communication facility of the portable terminal and the wireless communication apparatus move into a particular operation mode if communications do not occur therebetween at least for a predetermined time period. In monitoring the signal level of the wireless signal from the wireless communication apparatus in the particular operation mode, the portable terminal reduces a response speed at which to detect a signal level change. This causes the wireless communication apparatus to delay issuing a request for an increase in transmission power, thereby reducing unevenness of the working distance at which to alert a user to the unusual distance traveled between the two apparatuses or beyond which to limit the use of some functions of the portable terminal.
Abstract:
Provided is a plastic sheet for rear projection screens, which has a two or more multi-layered structure and which can be readily warped without being unfavorably swollen or waved. The plastic sheet is constructed to have a two or more multi-layered structure, in which the coefficient of linear expansion (at 20° C.) of one layer is higher by at least 1.0×10−6 mm/(mm·°C.) than that of any other layer. In one embodiment of the plastic sheet, the layer of which the coefficient of linear expansion is higher than that of any other layer contains a fine particulate rubber material having a diameter of from 0.1 to 100 &mgr;m to such a degree that the rubber material content thereof is higher by at least 0.5% by weight than that of any other layer.

Abstract:
A lenticular lens sheet capable of reducing the color shift and improving the overall light beam transmittance. The lenticular lens sheet has an incident side lenticular lens on its light beam incident side surface and further has an emergent side lenticular lens on its emergent side surface, with peak portions of the emergent side lenticular lens being formed at substantially convergent positions of the incident side lenticular lens. When an inter-lens distance at the sheet central portion is taken to be t.sub.0 and an inter-lens distance of an end portion of an viewable area of a rear-projection screen composed of this lenticular lens sheet is taken as t.sub.1, the rate of the inter-lens distances t.sub.0 and t.sub.1 is determined to satisfy 0.98.ltoreq.t.sub.1 /t.sub.0 .ltoreq.1.10.
