20120188849 | ULTRASONIC SENSOR AND ELECTRONIC DEVICE - The ultrasonic sensor includes: a plurality of transmission/reception dual-use elements, first electrode switches connected to the first electrodes of the transmission/reception dual-use elements; second electrode switches connected to the second electrodes of the transmission/reception dual-use elements; a control circuit; a transmitting circuit; a receiving circuit; a common-electrode connection wiring; and serial connection wiring. When an ultrasonic signal is to be transmitted, the control circuit connects the first electrode switches to the transmitting circuit, connects the second electrode switches to the common-electrode connection wiring so that the transmission/reception dual-use elements are connected in parallel to the transmitting circuit and the common electrode. When an ultrasonic signal is to be received, the control circuit connects the first electrode switches and the second electrode switches to the serial connection wiring so that the transmission/reception dual-use elements are serially connected to the receiving circuit. | 07-26-2012 |

20150063057 | ULTRASONIC MEASUREMENT APPARATUS, ULTRASONIC IMAGING APPARATUS, AND ULTRASONIC MEASUREMENT METHOD - An ultrasonic wave of a predetermined wavelength is transmitted toward an object from channels that are constituted by ultrasonic transducer elements, and reception waves of ultrasonic echoes relating to the transmitted ultrasonic wave are acquired from the channels. When information showing a normal mode or a low power consumption mode shows the normal mode, a first number of reception signals are added together with a weight that is computed in advance, and image generation is performed based on the reception signal obtained from the adding, and when the information shows the low power consumption mode, a second number of reception signals that is less than the first number is added together with a weight that depends on each reception signal, and image generation is performed based on the reception signal obtained from the adding. | 03-05-2015 |
20150063058 | ULTRASONIC MEASUREMENT APPARATUS, ULTRASONIC IMAGING APPARATUS, AND ULTRASONIC MEASUREMENT METHOD - Provided are an ultrasonic measurement apparatus, an ultrasonic imaging apparatus and an ultrasonic measurement method that achieve an increase in processing speed together with an increase in resolution and are user friendly. An image is generated by adding together, with a weight having a fixed value, reception signals obtained by ultrasonic echoes being received by an ultrasonic element array, and an area of interest is set within the area in which the generated image is to be displayed. When an area of interest is acquired, the reception signals received by the ultrasonic element array are added together with weights that depend on the reception signals, with respect to data forming the basis of the image to be displayed in the area of interest, and image generation is performed. | 03-05-2015 |
