A display apparatus includes a display unit that displays a predetermined target object to be gazed at by a subject, a gaze point detection unit that detects a position of a gaze point of the subject who observes the display unit, a region setting unit that sets a specific region corresponding to the predetermined target object, a determination unit that determines whether the gaze point is present in the specific region, an arithmetic unit that calculates gaze point data on the basis of a determination result of the determination unit, and a display control unit that displays an index at a position corresponding to the gaze point on the display unit if the gaze point data meets a predetermined index display condition.

Display apparatus, display method, and display program

A gaze detection apparatus performs a calibration operation including displaying a target image in multiple positions on a display screen sequentially, setting, in the display screen, corresponding areas corresponding to the target images displayed on the display screen sequentially, and calculating positional data of points of regard in display periods in which the respective target images are displayed; and determines, with respect to each of the target images, whether the positional data of the point of regard that is calculated in the calibration operation is present within the corresponding area.

Gaze detection apparatus, gaze detection method, and gaze detection program

Printed boards and are disposed in two layers inside a casing , and a selector cursor key and fixer keypad is provided on the cover . Selector cursor key switches are provided on the first printed board on the keypad side while a fixer key switch is provided on the second printed board . A protrusion portion of the keypad is made to penetrate a through hole of the first printed board so as to face the fixer key switch . The selector cursor key switches and the fixer key switch are arranged adjacently to each other in planar view so as to be able to be pushed and operated through one selector cursor key and fixer keypad

Switch unit and portable terminal device using the switch unit

A carrying case for portable electronic equipment is provided which is designed to allow a case carrier to stop an alarm or call sound produced from the electronic equipment without opening the carrying case. The carrying case has a protrusion formed on an inner wall of a cover at a given interval away from an operating button on the electronic equipment disposed within the carrying case. The cover is supported elastically by a case body with a given gap between front edges of the cover and the case body. The depression of the operating button of the electronic equipment through the protrusion to stop the alarm or call sound is achieved by pressing one of the cover and the case body against the other to decrease the gap therebetween. In another modified form, a window is formed in the bottom of the case body for allowing the case carrier to move the electronic equipment within the case body using a finger load, thereby bringing the operating button into engagement with the protrusion on the inner wall of the cover.

Structure of carrying case for electronic equipment

A charging control circuit is disclosed which comprises: a 1st connector (17) receiving an input supply power (34); a 2nd connector (30) for supplying a charging supply power (35) to charge either of a 1st (Ni-Cd) or 2nd (Lithium ion) battery (33a, 33b) and receiving a discharging supply power (36) from the battery; a kind detection portion (15) for detecting which of the 1st and 2nd kind of battery is to be charged; a voltage detection circuit for detecting an emf of the battery to be charged; a current detection circuit for detecting a charging current to the battery to be charged; a REF signal generation portion (15) for generating a REF signal (38) in accordance with outputs from the kind detection portion, the current detection circuit, and the voltage detection circuit; a difference providing portion (111) for providing a difference between the REF signal and the detected emf; and a charging supply power generation circuit for generating the charging supply power from the input supply power according to the output of the difference providing portion (111). The Ni-Cd battery is charged by a constant current and the lithium ion battery, by a constant current and a constant voltage (4.1 V). Completion of charging is detected by a drop of emf of Ni-Cd and decrease in the charging current to Lithium ion battery.

Charging control circuit

A watertight casing for electronic apparatus includes a first case, a second case and a cover. Sealing members are interposed between the first case and the second case, and between the second case and the cover, respectively. The first and the second cases and the cover are fastened tightly together. A printed board mounts electronic parts on one side thereof, and an air-zinc battery on the other side. The first case is provided with a recess portion into which the electronic parts on the printed board are received. Another sealing member is interposed between the second case and the other side of the printed board. The second case is provided with a through hole which is closed by the cover. The battery is received in the through hole in a sealed manner. The second case is further provided with a vent hole communicating the through hole with an atmosphere. At the opening end of the vent hole there is provided with a gas permeable waterproof sheet for permitting air to pass through but not permitting moisture to pass through.

Watertight casing for electronic apparatus

In an electronic apparatus case, the cover thereof mounted on one side of the case body through the intermediary of a hinge member so that the cover can be opened and closed by the same. Further, a substantially T-shaped lock member is rotatably mounted on the other side of the case body and, at the same time, an elongated lock hole is formed on the side of the cover corresponding to the lock member, so that the cover can be secured in position by allowing the head section of the lock member to pass through the lock hole of the cover and rotating the lock member by 90.degree..

Cover device for electronic apparatus case

A waterproof switch apparatus for an electronic device comprises at least one push-button for switching, a sheet-like water sealing member groove-engaged with the shaft portion of the push-button, and a holding member for holding the water sealing member by pressing the outer peripheral portion of the water sealing member against the device body. An excellent waterproof feature and a thin shape of the waterproof switch apparatus can be obtained.

Waterproof switch apparatus for electronic device

A battery holder for electronic apparatus for holding a coin-shaped battery includes a battery case which is provided with at least two protrusions, the coin-shaped battery being inserted in such a way that it is placed under these protrusions. Electrode terminals exert a resilient force so that the coin-shaped battery may be secured in position while maintaining satisfactory contact with the electrode terminals.

Battery holder for electronic apparatus

A watertight casing for electronic apparatus includes a first case, a second case and a cover. Sealing members are interposed between the first case and the second case, and between the second case and the cover, respectively. The first and the second cases and the cover are fastened tightly together. The first case is provided with a recess portion into which a printed circuit board is received. The printed circuit board mounts electronic parts on one side thereof, and a battery on the other side. Another sealing member is interposed between the second case and the other side of the printed circuit board.
