Abstract: The disclosed apparatus may include (1) a cage designed to hold an optical module, (2) a ramp that is secured to the cage and supports a heat sink such that the heat sink is capable of moving along the ramp, and (3) at least one spring having one end coupled to the ramp and another end coupled to the heat sink, wherein (A) prior to insertion of the optical module into the cage, the spring exerts a force at least partially directed along an axis of insertion of the optical module and (B) insertion of the optical module into the cage moves the heat sink along the ramp such that the force exerted by the spring (I) rotates away from the axis of insertion and (II) presses the heat sink against a surface of the optical module. Various other apparatuses, systems, and methods are disclosed.

Abstract: Methods and systems that reduce the effect of phase noise in radar receivers. The received phase noise spectrum is modulated with periodic nulls due to the two way range delay function. The system and method include strategically positioning the nulls of the delay function to cancel portions of phase noise power spectral density, the portions of the power spectral density of the phase noise being selected so that effect of phase noise in radar sensitivity is reduced.

Abstract: A mechanism for securing a handle to a head, particularly of a lacrosse stick, comprises a shaft having a wedge portion positioned at a distal end thereof, a binding plate positioned adjacent to said shaft, and a means for moving said wedge portion in a longitudinal direction relative to said binding plate. Longitudinal movement of said wedge portion causes latitudinal movement of said binding plate, thereby binding said handle to said head. Such a mechanism can be used in a method for securing and maintaining secure the joint between a handle and a head, either in a new lacrosse stick or as a retrofit.

Abstract: A talking trading card playing system consists of a portable card player and a plurality of trading cards. Each card includes a card body having front and back surfaces, flexible sheets affixed to the front surface and to the back surface of the housing, and a voice chip for storing and generating sound patterns. The portable player comprises a power source located in the housing for supplying electrical power to the voice chip, and sound generation components. The subject trading card and player may be activated by aligning the card with electrical contacts on the face of the player, thereby establishing electrical contact between the card and the player.

Abstract: A fuel injector includes an injector housing having a plunger assembly disposed within a central axial bore and including a lower plunger, an intermediate plunger, and an upper plunger. The lower plunger reciprocates within the central bore to meter a variable quantity of fuel during downward portions of the reciprocating motion. A timing spring is wound around the upper portion of the lower plunger to bias the lower plunger upwardly. A timing chamber formed between the upper and intermediate plungers receives timing fluid to create a hydraulic link between the plungers. Timing fluid exits the timing chamber through a central passage, which may have a reduced area regulating orifice, formed through the intermediate plunger, which is ordinarily closed by a valve mechanism. The valve mechanism is acted upon in part by the timing spring. To improve the pressure regulation using a higher spring load and to accommodate a larger area drainage passage, a valve spring biases closed the passage.
