  • Patent number: 9315115
    Abstract: A power assist device for assisting a user to operate an object. The power assist device includes a pressure sensor that detects an operating force applied to the object by the user; a motor that outputs and applies a motive force to the object; and a controller. The controller records a history of the operating force detected by the pressure sensor; detects a periodically fluctuating component of the operating force based on the history of the operating force; calculates a component of a current operating force caused by motion of the user operating the object; calculates a correction value that excludes the component caused by motion of the user from the current operating force; calculates a power assist force based on the correction value; and outputs the power assist force as the motive force of the motor.

  • Patent number: 9242561
    Abstract: A manually propelled vehicle may include a vehicle body, a left drive wheel and a right drive wheel, a wheel driver that drives the left and right drive wheels, a sensor that detects a user behind the vehicle body, and a controller that determines whether the user is behind the left or right drive wheel based on a detected result of the sensor. When one of the left or right drive wheel moves backward and the controller detects that the user is behind the one of the left or right drive wheel, the controller suppresses or stops the wheel driver from driving the one of the left or right drive wheel.

  • Patent number: 9186992
    Abstract: A walking assistance moving vehicle includes a walking assistance moving vehicle main body with a pair of drive wheels, a drive wheel rotational speed sensor, a turning sensor, and a controller. The drive wheel rotational speed sensor senses drive wheel rotational speed of each of the drive wheels. The turning sensor directly senses at least one of a first lateral acceleration and a first turning angular velocity. The controller indirectly acquires at least one of a second lateral acceleration and a second turning angular velocity based on the drive wheel rotational speed sensed by the drive wheel rotational speed sensor. The controller performs a first control to decelerate or stop drive of the drive wheels based on a comparison of the first turning angular velocity and the second turning angular velocity or a comparison of the first lateral acceleration and the second lateral acceleration.

  • Patent number: 8305494
    Abstract: A broadcast receiving device includes a first receiving unit, a second receiving unit, a display control unit, an audio determination unit, a switching determination unit and a switching execution unit. The display control unit displays a first image corresponding to a first television broadcast received by the first receiving unit on a main screen in a monitor, and displays a second image corresponding to a second television broadcast received by the second receiving unit on a subscreen in the monitor. The switching determination unit compares a first audio corresponding to the first television broadcast with a second audio corresponding to the second television broadcast, and determines whether or not the second audio is to be outputted instead of the first audio. The switching execution unit executes audio switching processing based on a determination result of the switching determination unit so that the second audio is outputted instead of the first audio.

  • Patent number: 8068717
    Abstract: A television program recording/reproducing device displays a reproduction program selection screen containing a title list image, a cursor image, frame images for initial letter selection and frame images for second letter selection. The title list image displays multiple title images sequentially in alphabetical order. One frame image for initial letter selection is displayed for multiple same titles, if any, while one frame image for second letter selection is displayed for multiple titles having the same initial letter, if any, in the title list image. The cursor image is moved on and between the title images and the both frame images. This television program recording/reproducing device allows a user to more effectively search for and find a desired television program to be reproduced, and can mitigate the burden on the user in an operation of reproducing a television program.

  • Patent number: 7559071
    Abstract: In a broadcasting receiver having a function to set and select an operation mode of the receiver for each user based on input by a plurality of users, the operation mode is selected for each user to make a user setting and stored in a memory in correlation with a predetermined input pattern of an operation key. When having received a user's input in the predetermined pattern, the receiver refers to the memory to select a user setting that corresponds to this input pattern, thus switching the operation mode. It is thus possible to identify the operation mode for each user in use by simple operations.

  • Patent number: 7515212
    Abstract: A digital broadcast receiver selects a language in which captions are displayed on a monitor on the basis of a language designated by a user for caption output (caption selecting means). Further, the digital broadcast receiver selects a language in which audio is output through a speaker on the basis of a language designated for audio output (audio selecting means). The digital broadcast receiver is designed so that the language designated for caption output and the language designated for audio output are set as a designated language that is unified (designated language setting means). Therefore, a user can designate a language for caption output and a language for audio output at the same time in only one operation to input a designated language. Accordingly, the necessity for separately inputting a language designated for caption output and a language designated for audio output can be avoided to eliminate the inconvenience to a user.
