An operation control apparatus () includes a data acquisition unit () and an apparatus control unit (). The data acquisition unit () acquires first congestion data. In a present example, the data acquisition unit () generates the first congestion data by processing an image generated by an image capture unit. The image processing performed herein includes, for example, processing of counting the number of persons in a crowd. The apparatus control unit () controls an apparatus to be controlled by using the first congestion data. For example, when the first congestion data exceed a reference value, the apparatus control unit () reduces the number of operating apparatuses to be controlled and lowers a response speed of the apparatus to be controlled in such a way that the number of persons moving from a second area to a first area per unit time decreases.

Operation control apparatus, operation control method, and non-transitory computer readable medium

A control apparatus () computes a waiting time index value for each of a plurality of gates () for entering an area (). The control apparatus () detects, from among the plurality of gates (), a first gate () and a second gate () of which relation between the waiting time index values satisfies a first criterion. Herein, the waiting time index value of the first gate () is greater than the waiting time index value of the second gate (). The control apparatus () causes a terminal () associated with the first gate () to output priority use information, which allows prioritized use of the second gate ().

A required time prediction apparatus (2000) acquires utilization facility information and assumed date and time information. The utilization facility information is information enabling to determine a departure facility and a destination facility. The assumed date and time information is information enabling to determine an assumed departure date and time assuming departure from the departure facility or an assumed arrival date and time assuming arrival at the destination facility. The apparatus (2000) estimates a waiting time at each facility being present between the departure facility and the destination facility, regarding a case of assuming departure from the departure facility at the assumed departure date and time, or a case of assuming arrival at the destination facility at the assumed arrival date and time. Then, the apparatus (2000) computes, based on the estimated waiting time, a predicted required time from departure from the departure facility to arrival at the destination facility.

An electronic apparatus is provided with a base unit and a display unit. The base unit has an opening formed on the upper surface. The display unit incorporates a display device and supported by the base unit. The display unit is rotatable between a first position where it is tilted down in such a manner as to cover the upper surface of the base unit and a second position where it is raised in such a manner as to expose the upper surface. The display unit includes a projection portion which is inserted into the opening when the display unit is rotated to the first position. A switch for turning the display device on or off is arranged inside the base unit. The switch includes an operation element opposed to the opening of the base unit. When the display unit is rotated to the first position, the operation element is pushed by the projection portion, thereby turning off the display device.

In a battery-driven portable computer, a battery pack is constituted by m battery sets connected in series each including n lithium-ion secondary battery cells connected in parallel. A voltage monitor for monitoring the voltage of the terminal electrode of each battery set and a charger for independently appropriately charging each battery set in accordance with a monitor result are arranged, thereby realizing battery driving by a lithium-ion secondary battery pack having a large capacity. A computer system monitors the voltages of the battery cells which are part of a secondary battery by comparing the battery voltages with a predetermined voltage value in order to detect overdischarge (undervoltage) or overcharge (overvoltage), outputs this information outside of the battery pack, and terminates processing prior to a circuit disconnect.

A connector mounted on a system board has terminals the number of which corresponds to the total sum of key matrix control signal lines and pointing stick control signal lines. The key matrix control signal lines and pointing stick control signal lines are connected together to the connector. Both a keyboard interface and a pointing stick interface can thus be achieved by the single connector, resulting in improvement in mounting efficiency, decrease in cost and simplification in assembly process.

The case includes a peripheral wall having a connector port and a storing portion arranged therein. A connector is located in the case. The connector opposes the connector port. A connector cover is supported by the case. The connector cover is movable among a closed position where the connector is covered, an open position where the connector is exposed to the outside of the case and a storing position in the storing portion where the connector cover is housed.

In a computer system, when an expansion unit is connected to a computer main body by an interface card, power supply control and I/O port selection are performed at the start of the computer system. In the power supply control, when an expansion power supply of the expansion unit is turned on, a first voltage is supplied to a main power supply of the computer main body. When the main power supply is turned on, main voltages are supplied to computer main body elements from the main power supply in response to the main voltage, and a second voltage is supplied to the expansion power supply through the interface. In response to the second voltage, expansion voltages is supplied to expansion unit elements, and an interface voltage is supplied to the interface. After the power supply control is completed, the I/O port selection is performed. The port addresses of the I/O ports in the computer main body are compared with the port addresses of the I/O ports in the expansion unit. If both port addresses coincide with each other, the I/O ports in the computer main body are disabled, and the I/O ports in the expansion unit are enabled.

An electronic system includes an electronic apparatus body and an external expansion unit. The electronic apparatus body has a bottom surface and a rear surface. A first connector is arranged on the rear surface. The external expansion unit has a first surface opposing the bottom surface, and a second surface opposing the rear surface. The external expansion unit has a second connector which is detachably connected to the first connector. The external expansion unit has an engaging device. The engaging device is movable between the first position where the engaging device is separated from the bottom surface and the second position where the engaging device is engaged with the bottom surface to pull the electronic apparatus body toward the second surface. The external expansion unit has an operation mechanism for selectively moving the engaging device to the first and second positions.
