In one aspect, the present invention comprises a method for tuning a power line communication inductive signal coupling device comprising a coupler and a plurality of capacitors, the method comprising: passing a carrier frequency signal through the coupler; sensing an amplitude of the signal; and switching the capacitors until the amplitude of the signal reaches a maximum. In various embodiments: (a) the signal is transmitted by a second transmitter, and the method further comprises switching to a first transmitter for data transmission; (b) the signal is received by a receiver after passing through the coupler; and (c) the capacitors are switched by a relay controller receiving commands from a microprocessor.

The present invention comprises systems and methods related to monitoring of energy usage on a power line. In a preferred embodiment, this system comprises (a) an electronic microprocessor-controlled digital electricity metering device coupled to the power line and comprising a non-volatile non-battery-powered data-storage device, wherein the metering device is capable of interval metering and of receiving a data request and transmitting data in response to the request over the power line; and (b) a data collector (preferably, a transponder) coupled to the metering device via the power line. The data collector is preferably capable of (i) receiving data from and transmitting data to the metering device over the power line, (ii) storing data received from the metering device over the power line, and (iii) receiving data from and transmitting data to a remotely located computer (preferably, a billing computer).

A display, such as a Christmas display, comprises a plurality of ornaments (14), each including a striker (18), a pair of bells (26, 27) disposed in spaced relation from the striker (18) and a means (46) responsive to an electrical signal from a control unit (12) for moving the striker into contact with one or the other of the bells (26, 27), at least some of the bells on the ornaments having different frequencies such that sequentially striking the bells (26, 27) plays a tune, such as a Christmas carol. The ornaments are preferably distributed about a Christmas tree, though alternatively they may be placed on a flat surface.

Decorative display and ornament therefor

A holiday action and musical display (10) comprising a plurality of separate display units (40, 42, 44, 46) electrically connected to a central control unit (12). Each display unit contains a figurine (147) resembling a character representation which is capable of being moved from a first position where the figurine is partially blocked from a user's view, to a second position where the figurine is visible to a user. The central control unit accesses several pluralities of stored sounds and phrases which are stored in electronic memory (305), with the sounds of each plurality having a common timbre distinct from the timbres of the other pluralities of sounds, and with each timbre being associated with a particular character representation. The accessed sounds are played on a speaker (12) and the central control unit synchronizes the movements of the figurines with the accessed sounds so that the figurines appear to be jointly singing one of a plurality of stored melodies.

Holiday action and musical display

An apparatus is provided for evaluating the tonal characteristics of an object with respect to a nominal tone which comprises a striker for causing the object to generate an audio signal and a microphone for inputting the audio signal. A reference signal generator generates plural reference signals in accordance with the nominal tone, and those signals are mixed with the audio signal by a mixing circuit. The accuracy of the audio signal with respect to the nominal tone is evaluated in accordance with the audio signal mixed by the mixing circuit.

Apparatus for determining tonal characteristics of an object and method

The present invention is a Christmas display (10) resembling a ski-lift and ski-slope, for use in conjunction with a Christmas tree (92). The display (10) comprises a track (12) having a first end (14) and a second end (16), wherein the first end is at a higher elevation than the second end, and a lift (18) disposed between the first end (14) and the second end (16). The device also comprises a plurality of figurines (30) having a base configured for slidable movement along track (12) from the first end of track (12) to the second end of track (12) whereby the lift (18) transports the figurine (30) back to the first end (14) of the track (12) in a continuous manner. In the preferred embodiment, the display also comprises a support mechanism (90) for supporting the display on a Christmas tree.

An electronic percussion synthesizer assembly incorporates a novel structure for supporting the drum heads. The novel supporting structure comprises a spider assembly (83) comprised of a plurality of legs (150) joined at one end for defining a hub (152) and secured at their free ends to the perimeter of the drum head (65) on the underside thereof. The spider assembly (83) minimizes mechanical damping of the striking surface and, where a plurality of drum heads (62, 63, 64, 65) are used, also minimiizes 'cross talk' between the drum heads. A novel foot pedal control (120) for altering the sounds produced by the drum head is also disclosed.

A microprocessor-based electronic guitar generates a music signal for driving an integral speaker. The electronic guitar includes a housing defining a neck and a body, a plurality of manually actuatable strings secured to the body, and a plurality of pushbuttons distributed along the neck, the strings and pushbuttons being operable by the player for controlling the composition of the music signal generated by the microprocessor. The electronic guitar is playable in a chord mode wherein the microprocessor, upon striking the strings, generates a music signal corresponding to chord sounds, a lead mode wherein the microprocessor, upon striking the strings, generates a music signal corresponding to individual notes, and an automatic mode wherein the microprocessor, upon striking the strings, generates a predetermined chord progression defining a stored melody.

An intruder alarm includes a circuit with a photoresistive cell located in a housing with a piezoelectric crystal sound generator and battery to power the circuit and sound generator. A telescope concentrates light from a distance in a limited field of view upon the photoresistive cell to trigger the piezoelectric crystal sound generator when light intensity on the cell changes sufficiently from an ambient light intensity level.

A method and apparatus are disclosed for sensing, sampling and performing calculations on a parameter of a physical quantity at a plurality of remote locations comprising a plurality of remote sensing units and at least one processing unit linked to said plurality of remote sensing units via a two way communication link. Parameters of a physical quantity are sensed and sampled, calculations are performed and accumulated and transmitted, on demand, provided to the processing unit using a plurality of frequency bands one of which is identified as having valid data.

Method and apparatus for remote measurement

A digital rectangular wave musical tone generator (10) activates a speaker (12) to produce sounds of aural quality similar to musical instruments, while varying the intensity of light output from a light-emitting diode (13). The intensity variations of this light controls the resistance of a photoresistor (16), which varies the power supplied to decorative lights by a power control device (19), thus varying the intensity of the decorative lights in synchronism with the sound.
