    • An apparatus for tracing position and direction of a target object through an RF signal includes two loop antennas and a position and direction determination part. The two loop antennas receive the RF signal transmitted from the target object and are perpendicularly coupled to each other. The position and direction determination part calculates two RF signal intensities received through the respective two loop antennas for comparison, and then determines that the target object transmitting an RF signal is placed in a center direction between the two loop antennas if the two RF signal intensities are the same, and otherwise determines that the target object is placed in a front direction of the loop antenna having a relatively higher RF signal intensity.
    • 通过RF信号跟踪目标物体的位置和方向的装置包括两个环形天线和位置和方向确定部分。 两个环形天线接收从目标对象发送的RF信号并且彼此垂直地耦合。 位置和方向确定部分计算通过相应的两个环形天线接收的两个RF信号强度进行比较,然后如果两个RF信号强度是两个RF信号强度,则确定发送RF信号的目标对象位于两个环形天线之间的中心方向 相同,否则确定目标对象被放置在具有较高RF信号强度的环形天线的前方。

    • A process for the preparation of a substantially free flowing particulate flavor by mixing an oil soluble flavor with a melted edible fat having a melting point from about 30° C. (85° F.) to 93° C. (200° F.) to form a solution of the oil soluble flavor in the melted fat, cooling the solution of the oil soluble flavor in the melted fat, with the addition of a super-cooling agent with agitation during cooling, to produce solid particles having an average diameter of from about 0.1 to 10 cm, and then, if desired, grinding these particles with a super-cooling agent to produce the substantially free flowing particulate flavor whose particles have an average diameter of less than 1 mm.
