An optical element is arranged in such a manner that a screen thereof can be hardly observed from a predetermined direction, and a deterioration of an image quality caused by moire does not occur. The optical element is constituted by a first polarizing layer, a second polarizing layer, and a liquid crystal layer arranged between these two polarizing layers. In the optical element, absorption axes of the first polarizing layer and the second polarizing layer are located parallel to each other; the liquid crystal layer is made of hybrid-aligned discotic liquid crystal; and an alignment axis of the liquid crystal layer is located parallel to, or perpendicular to both absorption axes of the first polarizing layer and of the second polarizing layer.

A method for preventing obesity related to infection by an adipogenic adenovirus includes assaying a sample from a person to determine whether the person has been previously infected with an adipogenic adenovirus, and if the person has not been previously infected, providing the person with at least one sensor positioned to detect when a person's hand approaches a predetermined distance from the person's face. By warning the person of undesired hand-to-face contacts, the person is able to reduce the incidence of obesity related infections. Other embodiments are directed to a kit for preventing obesity caused by infection with an adipogenic adenovirus, such kit including a container for assaying an agent indicating the presence of antibodies to Ad-36, and a sensor positioned on an item selected from the group consisting of one of a hat, a writing instrument, eye glasses, a belt, sunglasses, a bra, a shirt, and a tie.

Embodiments of the invention provide for allocating spectrum in a wireless communication system that supports simultaneously at least a first mode of operation and a second mode of operation. Logic is arranged for determining a proportion of spectrum required for the wireless communication unit to operate simultaneously in both the first mode of operation and the second mode of operation. Logic for allocating spectrum allocates a temporary guard band between a first portion of spectrum for the first mode of operation and a second portion of spectrum for the second mode of operation for use whilst the wireless communication unit operates simultaneously in the first mode of operation and second mode of operation.

A seat air conditioner for a vehicle seat includes a blower unit which has a blower fan and an air discharge duct, a vibration isolation unit arranged between the blower unit and a cushion member of the seat, and an accordion duct which is arranged between the air discharge duct and an air passage defined in the cushion member. The blower unit is disposed at an opposite side to the cushion member with respect to seat spring members of the seat. Air blown by the blower fan flows toward a plurality of blowing-out openings formed at a surface cover member of the seat, through the air discharge duct, the accordion duct and the air passage formed in the cushion member.

Both a connection server and a relay connection server are installed in an IP transfer network; a function similar to a line connection control of a subscriber exchanger is applied to a connection server; a function similar to a line connection control of a relay exchanger is applied to the relay connection server; and a terminal-to-terminal communication connection control method with using the IP transfer network is realized in such a manner that a telephone set and a terminal such as an IP terminal and a video terminal transmit / receive an initial address message, an address completion message, a call pass message, a response message, a release message and a release completion message, which can be made in a 1-to-1 correspondence relationship with line connection control messages of the common line signal system. Furthermore, while an address administration table is set to a network node apparatus of an IP transfer network, means for registering addresses of the terminals into this address administration table is employed, so that an IP packet communication by a multicast manner can be realized with improving information security performance.

A surface cleaning apparatus is provided wherein a uniflow cyclone comprises a cyclone chamber defined by a longitudinal axis, the cyclone chamber having a dirt outlet that has a variable length in the direction of the longitudinal axis. A cyclone chamber having a barrier wall facing the dirt outlet of the cyclone chamber is also provided.
