摘要： A transport header analyzing unit (133) analyzes, on the basis of the TCP header of transport data transmitted from a transmitter terminal (100) to a receiver terminal (200), whether the transport data is an acknowledgement response in a TCP communication. If the transport data is not an acknowledgement response, a synchronization pre-processing unit (134) determines, on the basis of the TCP header of the transport data, whether synchronization information, which is required to operate in a power saving mode together with an access point (300), is added to the IP header of the transport data. A synchronization information processing unit (235) adds, to the IP header of the transport data indicating an acknowledgement response to received data that is received from the transmitter terminal (100), the synchronization information that is required to operate in the power saving mode together with the access point (300).

摘要： An infrared detection unit includes a base carrying an infrared sensor element, and a cap configured to be fitted on the base to surround the infrared sensor element. The cap has a top wall with a window in which a semiconductor lens is fitted to collect an infrared radiation onto the infrared sensor element. The semiconductor optical lens is formed from a semiconductor substrate to have a convex lens and a flange which surround said convex lens. An infrared barrier is formed on the semiconductor lens to block the infrared radiation from passing through the boundary between the circumference of the convex lens and the window. Accordingly, the infrared sensor element can receive only the infrared radiation originating from a detection area intended by the convex lens.

摘要： A semiconductor substrate is anodized to be shaped into an optical lens. Prior to being anodized, the substrate is finished with an anode pattern on its bottom surface so as to be consolidated into a unitary structure in which the anode pattern is precisely reproduced on the substrate. The anodization utilizes an electrolytic solution which etches out oxidized portion as soon as it is formed as a result of the anodization, to thereby develop a porous layer in a pattern in match with the anode pattern. The anode pattern brings about an in-plane distribution of varying electric field intensity by which the porous layer develops into a shape complementary to a desired lens profile. Upon completion of the anodization, the semiconductor substrate is shaped into the lens by etching out the porous layer and the anode pattern from the substrate.
