Granted: 1999-09-14
Abstract: A flashlight holder clamp assembly having a mounting bracket which contains one or, optionally, two elastomeric substantially spherical gripping members having a centrally disposed cylindrical channel therein for receiving a portion of the barrel of a small flashlight and for receiving a cylindrical support member. The gripping members also define a plurality of uniformly spaced longitudinal slots which communicate along their inner ends with the central channel so as to allow the gripping member to be uniformly constricted by the mounting bracket upon clamping the flashlight holder clamp assembly to a cylindrical member, such as a bicycle handlebar.      The end of the flashlight holder clamp assembly which contains the spherical gripping member has two or four apertures formed therein to accommodate the portions of the flashlight barrel projecting outwardly from the spherical gripping member and allowing the flashlight to be directed in any one of four general directions, either perpendicular to a longitudinal direction of the bicycle handlebars or in a direction along the longitudinal direction of the bicycle handlebars. The lower portion of the flashlight holder clamp assembly defines a pair of cooperating gripping surfaces which clamp onto the tubular member as the mounting bracket is tightened about the spherical gripping member by a suitable tightening means, or may also have two or four apertures to accommodate the support member and to allow the mounting bracket to be adjusted rotationally about the axis or perpendicularly to the axis of the support member.

The automatic exposure adjusting apparatus also outputs a second mean value weighted every area in accordance with a luminance distribution in the image sensed picture. The automatic exposure adjusting apparatus controls the adjustment of exposure based on the first and second mean values. Such weighting of the luminance level in accordance with the luminance distribution is carried out based on the fussy inference.

Title: Coriolis mass flow rate meter having a substantially increased noise immunity
Inventor: ROMANO PAUL
IPC: G01F1/84
Filed: 1990-05-23
Granted: 1996-07-02
Abstract: Apparatus and accompany-ing methods for use therein for a Coriolis mass flow rate meter (5) which is substantially immune to noise, and more particularly, to such a meter that is substantially unaffected by noise that occurs at substantially any frequency differ-ent from a fundamental frequency at which the flow tube(s) (130, 130') in the meter vibrates. Specifically, the meter (5) relies on measuring mass flow rate by determining the phase difference that occurs be-tween real and imaginary compo-nents of the discrete fourier trans-form (DFT) of both the left and right velocity sensor waveforms evaluated at the fundamental fre-quency at which the flow tubes vi-brate. The fundamental frequency is located, during an initialization operation, by providing a power spectrum, determined through use of the DFT, of one of the sensor signals and then selecting that frequency at which the magnitude of the power spec-trum reaches a maximum value. In addition, the frequency at which both velocity sensor signals are sampled is readjusted in re-sponse to any change in the phase of one of the velocity sensor signals, as transformed using the DFT, in order to assure that the sampling frequency always remains substantially equal to a pre-defined integer multiple of the fundamental frequency. Further-more, the meter, through use of the numerical value of any such phase change, also provides a density indication which is also substantially immune to such noise.

Title: Air massaging device with a precise pressure control
Inventor: SENOUE MASAHARU
IPC: A61H7/00
Filed: 1992-05-29
Granted: 1996-05-28
Abstract: An air massaging device having at least one inflatable air bag adapted to be laid against a portion of the human body.  The device includes an air pump generating a pressurized air and a distributor valve which has an open position of feeding the pressurized air to the air bag and a closed position of allowing the pressurized air to be discharged from the air bag to the atmosphere in order to repeat inflating and deflating the air bag.  A single pressure sensor is disposed upstream of the distributor valve to monitor a pressure level developed on the side of the air pump.  A control circuit is included to activate the air pump on a time-period basis in order to give a desired pressure level to which said air bag is inflated.  The control circuit operates to provide one or more initial inflation cycle and subsequent inflation cycles alternated by deflating cycles of deflating the air bag.  During the initial inflating cycle, the air pump is firstly activated for a pre-determined standard inflation time period to inflate the air bag and then stops while keeping the air bag inflated for a short time interval in which the pressure level of the air bag is monitored.  In the subsequent inflating cycles, the air pump is activated for a varying inflation time period which is determined as a function of the previous inflation time period, a desired target pressure level selected by a user, and the pressure level monitored in the previous inflation cycle.
