An apparatus to automatically close a refrigerator door when the door is opened at a predetermined angle or less. The apparatus includes a hinge mechanism having a first hinge shaft provided at the door, which allows the door to be coupled to a refrigerator cabinet and allows the door to be rotated about the hinge shaft, a tension spring provided at the refrigerator cabinet to apply the door with a tension force for closing the door, and a unit to asborb shock generated when the door is closed by the tension spring, and the a unit to absorb shock includes a housing coupled to the cabinet, and a movable shaft which is received in the housing at its one end and connected to the door at the other end to be linearly moved in the housing, and wherein the tension spring is connected to the cabinet at its one end and connected to the movable shaft at the other end to apply the door with a tension force of closing the door. Thus, when the door is opened at an angle of 90 degrees or less, the door is automatically closed and when the door is opened at an angle greater than 90 degrees, the door remains in its position. Accordingly, use of the refrigerator is convenient, and the maximum rotation angle of the door can be controlled according to a user's desire.

An apparatus for controlling droplets allows the phase difference between a calibration signal and its signature signal on a detector to be minimized, or the amplitude of the signature signal to be maximized, by adjusting the droplet charging means of the device, or the droplet generation means, and the signals on either. The apparatus converts a stream of fluid into a stream of droplets under the influence of a droplet stimulation signal imposed onto the droplet generating means. Droplets are subsequently signal-wise charged under the influence of a droplet charging signal imposed on the droplet charging means. The charged droplets are then deflected. The calibration signal is imposed onto the stream of droplets. The calibration signal has characteristics that do not appreciably affect the trajectory of the stream of droplets, thereby ensuring that the placement accuracy of the individual droplets is a maintained. The calibration signal further has a signal phase that is independent of the droplet charging signal. A charge detection means is used to extract a charge detection signal from the at least a part of the droplets. The charge detection signal is filtered to extract a signature signal of the calibration signal. The phase control system then varies at least one of the droplet generation means, droplet stimulation signal, droplet charging means and droplet charging signal until the phase between the signature signal and the calibration signal is minimized. A plurality of streams of droplets may be controlled by the method of the invention.

An athletic training system used when practicing athletic training activities. The athletic training system includes a belt and means for maintaining the belt in place and prevent the belt from rotating or slipping during application which can occur due to the forces placed on the belt during application. The belt is secured beneath the user's waist and partially surrounds each of the user's thighs. To further maintain the belt in place, a pair of thigh straps depend about the inside of the users thighs to partially surround the thighs. First and second hip members outwardly extend from the side-ends of the belt. Each of the hip members form a triangle configuration with a part of the triangle extending from above the user's hip joint and a part of the triangle extending from below the user's hip joint during application. An elastic resistance band includes one end that is secured to a support, and an opposite end releasably attached to one or both of the hip members.

A multi-angle ultra wide band antenna for electronic devices is disclosed. The said antenna cover all mobile bands worldwide: 700 / 850 / 900 / 1700 / 1800 / 1900 and 2100 MHz and with sufficient bandwidth to include the 2400 and 2500 MHz mainly used in wireless networks, having a radiated element supported by a first substrate and expanding into a spatial geometry for transmission and reception of radio signal. An antenna base has a plurality of first solder pads on a second substrate for physical attachment to a printed circuit board and a second solder pad electrically connected to a terminal of said antenna to radio circuitry feed point, with compatible surface mount technology. The first and second substrates are joined by a bending line as a single substrate, where the said first substrate is allowed to be bent relative to the plane of the said second substrate.
