摘要:
The present invention relates generally to a system and method for determining the earliest time of arrival of a received signal in a wireless communications system. In particular, the present invention relates to a system and method for de-rotation of the carrier phase of a received signal to offset the effects of combining a received line-of-sight signal with various received multipath artifacts that may shift the complex phase of the received signal. The system and method of the present invention can improve the accuracy of the estimated time of arrival of a received signal by computing the time of arrival of the received signal at numerous different phase references and identifying the earliest of the computed times of arrival.

A method and system of determining and correcting modulation and offset effects in a received signal. A signal [s(n)] is received subject to modulation effects A on pulse shape or peak [p(n)] and vertical offset B due to multipath where “n” is a pulse rate or samples of the signal. A template of length N incorporates a replica of the original signal [s(n)] without multipath or vertical offset. The template is normalized and generates either an extended template or a balanced template. The extended template is correlated with the received signal [s(n)] by shifting the extended template along the received signal to estimate modulation effects of A at a particular time, n. The average difference between the template and the modulated signal [p(n)] is calculated to determine the magnitude of the offset B for a particular time, n.

A mouthpiece for reducing snoring is provided. The mouthpiece includes an upper guard configured to fit over the upper teeth of a user, a lower guard configured to fit over the lower teeth of the user, a spacer assembly provided between the upper guard or the lower guard to provide an air passage at a middle section of the mouthpiece, a first adjustable assembly attached to the left side of the upper guard and the left side of the lower guard, and a second adjustable assembly attached to the right side of the upper guard and the right side of the lower guard. The first adjustable assembly and the second adjustable assembly are operable to move the lower guard relative to the upper guard.

A front grille for a room air conditioning unit includes a planar front section, which includes an air inlet opening, an air outlet opening, and an opening configured to receive the unit's control panel when mounted on an air conditioning unit. The front section has a top wall, bottom wall, and left and right-hand side walls, each of which extend rearwardly of the front section and cooperate with one another to define a skirt element integrally formed with and extending rearwardly from the planar front section. An elongated recess is formed in the planar front section. One or more inserts, each of which is configured to be received in the recess in the front section, are provided. Each of the inserts has a distinguishing ornamental configuration thereon, which is different from the distinguishing ornamental configuration of the other inserts. Means are provided in the elongated recess and on each of the inserts for cooperating with one another to retain each of the inserts in the recess.

A method and apparatus are described herein for mounting a power supply within a PC chassis such that it is ratchetably rotatable. The chassis includes a pivot receptacle, a hook, and a dimple. The power supply is received by a mounting bracket which includes a corresponding pivot point, a curved slot having a relatively wide portion disposed at one end for engaging the hook of the chassis and a relatively narrow portion for retaining the hook during rotation of the power supply, and a plurality of shorter slots oriented in a curve for engaging the dimple of the chassis thereby providing the ratcheting action and preventing the rotation of the power supply until force is applied. In an alterative embodiment, the power supply is mounted to be translatable and rotatable. The chassis includes two cams, and a hook. The power supply is received by a mounting bracket which includes two cam slots each having a straight portion and a curved portion for engaging the cams of the chassis, and a straight slot having a relatively narrow portion that engages the hook of the chassis and a relatively wide portion that allows the hook to disengage from the slot. The hook and slot prevent rotation, ensuring the translational movement as the cams move along the straight portion of the cam slot. The cams reach the curved portion of the cam slots at the same time the hook reaches the relatively wide portion of its slot and disengages, thus allowing rotation. A lip disposed on the power supply supports the weight of the power supply, as well as helping guide the power supply during the translational motion.

An improved room air conditioner of the type having an indoor section and an outdoor section, which are supported by a basepan and which are separated by a partition. The indoor section includes an indoor fan and an evaporator coil and the outdoor section includes a condenser coil, an outdoor fan and a compressor. The air conditioner is made from two subassemblies, the first subassembly includes a basepan having an indoor region near the front of the basepan and an outdoor region near the back of the basepan. The compressor is supported in the outdoor region and a condenser coil is also supported in the outdoor region rearwardly of the compressor. The evaporator coil is supported in the indoor region and a refrigeration flow circuit interconnects the condenser, the evaporator coil and the compressor. The second subassembly includes a vertically extending partition having an indoor side, an outdoor side and an opening therethrough extending from one side to the other. The partition is configured to cooperate with the basepan to separate the indoor region from the outdoor region. An electric motor is mounted on the outdoor side of the partition. The motor has a drive shaft extending perpendicular to the partition with the first end extending through the opening so that it is on the indoor side of the partition and the second end on the outdoor side of the partition. An indoor fan is mounted to the first end of the drive shaft and an outdoor fan is mounted to the second end of the drive shaft. The second subassembly is configured to be assembled to the first subassembly by positioning the second subassembly in a position vertically spaced above the first subassembly and lowering it into alignment with the first subassembly with the outdoor fan forward of and adjacent to the outdoor heat exchanger, and the indoor fan rearward of and spaced from the indoor heat exchanger. The partition engages the basepan and is structurally attached thereto.

A cake covering assembly for protecting a cake from airborne pathogens includes a cover that is positionable over a cake. The cover is comprised of a fluid impermeable material to protect the cake from airborne pathogens. The cover has a plurality of candle openings each extending through the cover. A plurality of candle holders is provided and each of the candle holders has a receiver to insertably receive a candle. Each of the candle holders is insertable through a respective one of the candle openings having the receiver being spaced above the cover. In this way each of the candle holders can support the candle in a vertical orientation thereby facilitating the candle to be blown out by a user in the convention of blowing out birthday candles.
