Abstract: In a car navigation system (1), a position information detection means (11) detects position information on a vehicle using, for example, a GPS. A travel information history of the vehicle obtained based on the detected position information is accumulated in a travel information history means (15). When detecting an event such as start of an engine, an action prediction means (17) predicts a destination of the vehicle by referring to a route to the current time and to the accumulated travel information history. Commercial or traffic information regarding the predicted destination is acquired by an information acquisition means (18) from a server (2), and then is displayed on a screen, for example, by an information provision means (19).

Abstract: For cooking data provided via a communication network, use track records of the cooking data corresponding with their actual use status are accurately managed. When receiving a request for transmission of cooking data from a terminal (S11), a server transmits the cooking data to the terminal (S12, S13), and at this time receives use history data with a microwave oven for previously transmitted cooking data (S14). The server manages use track records of the cooking data based on use history data received from terminals.

Abstract: A small, low-cost, wide-range current sensor excellent in environmental resistance and noise resistance and high in accuracy, and an application device, a DC magnetic field is applied to two magnetic elements (1a, 1b) having a magnetic impedance effect by means of a magnet (3), while a negative feedback magnetic field is applied to both elements by means of a coil (2). The variation of the magnetic field depending on the external magnetic field applied to the magnetic elements (1a, 1b) is detected by detection units (7a, 7b) The difference between the output is amplified by a differential amplifier unit (8). Thus, detection is achieved in a wide range while eliminating the influence of the noise.

Abstract: The users are allowed to easily retrieve contents data such as recipe data. A personal computer (103) receives recipe data from a server (101) via a communication network (102), and stores the received recipe data in a memory card (104). The personal computer updates recipe hierarchical information (142) in the memory card (104), i.e., information which indicates classified levels of recipe data based on retrieval keys, with reference to overall hierarchical information (133), i.e., information which indicates the hierarchical relation of retrieval keys in the whole recipes, so that the newly stored recipe data is included in the recipe hierarchical information.
