Abstract: A computer-implemented method for streaming multimedia data is disclosed. The computer-implemented method includes identifying a high importance video segment yet to be streamed to a buffer, determining, based on a current network bandwidth, if the high importance video segment can be streamed at a video quality above a predetermined threshold, responsive to determining, based on the current network bandwidth, that the high importance video segment cannot be streamed at a video resolution above a predetermined threshold, determining if there is a low importance video segment yet to be streamed to the buffer prior to the high importance video segment, and responsive to determining that there is a low importance video segment yet to be streamed to the buffer prior to the high importance video segment, adjusting prefetching of the high importance video segment in order to stream the high importance video segment at the video resolution above the predetermined threshold.

Abstract: An earphone includes a housing and a microphone. The microphone is provided in the housing. The housing includes a hole that leads to the microphone. The hole has a shape in which a cross-sectional area expands, toward a back of a head of a user wearing the earphone, from the microphone toward an outside of the housing. The housing, in a case of being worn by the user, is located farther away from an external earhole, in an outside direction from a side of the head, than from an ear of the user.

Abstract: An earphone includes a driver body, an insertion portion extending from the driver body and configured to be inserted in an ear canal, a cover body covering the driver body and including, a first opening at a position corresponding to the insertion portion, and a projection configured to come into contact with a concha. The driver body is configured to attach and detach any of a plurality of types of cover bodies each including the projection with a height thereof projecting from the cover body, the heights of the projections of the plurality of types of cover bodies being different and increasing as a distance from the opening to the respective projection is increased.

Abstract: Headphones include at least one headphone unit each having a speaker unit, a chamber that covers a back surface of the speaker unit, a housing that is disposed on a side of the back surface of the speaker unit, in which the chamber is disposed, and that covers the chamber, and a vibration damper that connects the chamber and the speaker unit.

Abstract: A catalyst composition and its use as a dehydrogenation catalyst to increase normal olefin selectivity and reduce undesirable aromatic selectivity. The reduction in aromatic production allows for the elimination of a unit to remove aromatic compounds. The catalyst has a layered composition comprising an inner core, an outer layer bonded to the inner core, the outer layer comprising one or more transition alumina with at least two diffraction angle peaks between 32.0° and 70.0° 2?, wherein a first diffraction angle peak in that range is at 32.7±0.4° 2?, a second diffraction angle peak is at 50.8±0.4° 2?, and having a thickness of less than about 100 microns and having uniformly dispersed thereon said platinum catalyst and at least one promoter metal and having a concentration of the platinum catalyst of from about 0.00006 to 0.0005 gram of the platinum group metal on an elemental basis per meter square surface area of the outer layer.

Abstract: A method of controlling a motor having windings of a plurality of phases includes an estimation step of calculating a current vector norm from d-axis current and q-axis current flowing in the motor, calculating power loss from the current vector norm and the entire heat resistance of the motor, and estimating the maximum temperature of the windings of the plurality of phases based on the power loss and a transfer function having first or higher-order transfer characteristics, in the case where the motor is in a low rotation state, and a limiting step of limiting input power based on the maximum temperature estimated in the estimation step.

Abstract: A control device of an electric motor, including an electric motor, a drive portion that supplies power to the electric motor, a voltage commanding portion that controls the drive portion on the basis of a torque command, and control a drive torque of the electric motor, a current limiting portion that outputs a limiting signal for limiting power outputted by the drive portion in a case in which a current value between the drive portion and the electric motor exceeds a predetermined value, and a limiting permission determining portion that determines whether the current limiting portion permits or prohibits an output of the limiting signal to the drive portion, when the drive torque of the electric motor cannot satisfy the torque command in a case in which the current limiting portion outputs the limiting signal, the limiting permission determining portion prohibits the current limiting portion from outputting the limiting signal to the drive portion.

Abstract: The golf club head (14) of the present invention has a face portion (24) for striking a golf ball, a crown portion (18) connected to the face portion (24), and a sole portion (22) connected to the face portion (24). The ratio of either lower of a first equivalent rigidity of a crown member (18) and a second equivalent rigidity of a sole member (22) to the higher is equal to or less than 0.75. The present invention provides a golf club (10) provided with the hollow golf club head (14) capable of increasing the carry of a golf ball based on a technique for increasing the carry of a golf ball other than conventional ones such as adjustment of the loft angle and reduction in the thickness of the striking surface, and provides a method of designing such a hollow golf club head as well.
