Abstract: A musical system uses a musical instrument with a first communication link and music related accessory with a second communication link for transmitting and receiving the audio signal and control data. A controller within the musical instrument or music related accessory is coupled to the first communication link for receiving control data to control operation of the musical instrument and transmitting an audio signal originating from the musical instrument through the first communication link as a cloud storage recording on a server connected to the first communication link. The cloud storage recording is initiated by detecting motion of the musical instrument or presence of the audio signal. The cloud storage recording is terminated a predetermined period of time after detecting no motion of the musical instrument or absence of the audio signal. A user control interface configures the musical instrument and the music related accessory.

Abstract: A guitar has a control system with a control surface disposed over the guitar and connected to the control system. A gesture is performed over the control surface. The gesture is created by user interaction with the control surface, such as movement of one or more fingers. The operation of the control surface is selectable and generates electrical signals representative of the gesture. An audio signal generated by the guitar is modified in response to the control signal. A musical accessory, e.g., an amplifier, effects box, synthesizer, special effects, or speaker is coupled to the guitar. The control signal is sent to the accessory to modify and control properties of the accessory. A configuration of the accessory and a configuration of the guitar are modified in response to the control signal. The control system is programmed to output the control signal over a wireless network.

Abstract: An apparatus and method for biasing each amplifier of an amplification stage provides that the voltage across each current sensing element of each amplifier of the amplification stage is measured. For each pair of voltage measurements taken, a sum and difference is calculated, where the sum is processed to determine minima peaks and the difference is averaged. A portion of the sum term and the average of the difference term are summed to yield the individual bias current conducted by a first amplifier of the amplification stage. The difference between a portion of the sum term and the average of the difference term is calculated to yield the individual bias current conducted by the second amplifier of the amplification stage. The bias current conducted by the first and second amplifiers may then be individually modified manually, or conversely, may be modified automatically based upon the bias current measurements taken.

Abstract: An arrow rest for use with archery bows includes an arrow supporting launcher that provides vertical movement to dampen any up and down movement of the arrow shaft when it is shot from the bow, such as up and down vibrational movement which occurs as a result of using a mechanical arrow release aid. The launcher includes a V-groove to support and guide the arrow. The rest also includes a pair of flippers which extend generally upwardly and in the direction of arrow travel along opposite sides of the arrow shaft supported on the launcher to lessen the chance that the arrow shaft will slide off the launcher. Either feature of the rest can be used alone without the other.

Abstract: An archery bow stabilizer is made up of a plurality of blocks of a solid resilient material such as a rubber material joined together in end-to-end relationship. Threaded sleeves in each end of each block allow the blocks to be joined together and the joined together blocks to be secured to the handle riser of a bow in normal manner using threaded studs. Usually three to four joined blocks will provide satisfactory stabilization for most bows but more or less blocks may be used when desired. The invention also contemplates stabilizers with rubber or similar resilient material exterior surfaces to eliminate most noise created by the stabilizer during knock-around in the field.

Abstract: An archery broadhead has twelve broadhead blade receiving slots to receive a plurality of broadhead blades in selected slots. A variety of different orientations of two blades, three blades, four blades, or more can be used to assemble a desired broadhead. By providing blades of different weights and a selection of different weight points and collars, the archer is given the opportunity to create a broadhead of blade configuration and weight as desired. A spearhead point with only two cutting blades and convex faces between the blades provides improved cutting and penetration of a target.

Abstract: A special tuning point for archery arrows for use in tuning a bow, target shooting, and non-big game hunting has a weight approximately equal to a broadhead selected for use by an archer using and tuning the bow and has a balance point position ahead of the arrow shaft to which the point is secured approximately equal to that of the selected broadhead. The tuning point is secured to the forward end of an arrow shaft substantially identical to that used with the selected broadhead to form a tuning arrow. The tuning arrow is used in tuning the bow. In this manner, the bow is properly tuned for not only the tuning arrow, but also for the arrows with the selected broadhead.

Abstract: An archery bow is tuned by making a tuning arrow that either has a tuning point rather than a broadhead, wherein the tuning point compensates for the weight and balance of the broadhead, weight at the rearward portion of the arrow instead of fletching and which compensates for the weight and balance of the fletching, or both. This produces a tuning arrow having substantially the same weight and balance point as the arrows to be shot from the bow during normal shooting. The tuning arrow is used to tune the bow and because the weight and balance point are substantially equal to the weight and balance point of the arrows normally shot from the bow, the tune obtained using the tuning arrow is the correct tune for the normal arrows also.
