Golf balls and a system for finding golf balls and methods for making golf balls and methods for using such balls. In the case of one exemplary golf ball, the ball includes a shell and a core material which is encased in the shell and a tag which is disposed within the core material and which has at least one perforation. The tag includes a diode and an antenna which are coupled together. Another exemplary golf ball includes a shell and a core material which is encased within the shell and a tag which is within the core material and which includes an electrical element which is coupled to an antenna; the tag is detectable over a range of at least 20 feet from a handheld device, and the golf ball has high durability and substantially complies with the golf ball specifications of the United States Golf Association.

Apparatuses, methods and systems relating to findable golf balls

Golf ball locators and components of such locators and methods of operating such locators and processing signals within such locators. In one aspect of the inventions described herein, an exemplary method of initializing a golf ball locator includes receiving received RF signals while also transmitting signals used to locate balls and determining a parameter representative of received signal strength of the received RF signals and setting a threshold to determine when subsequent received signals are to cause an indication of golf ball detection. In another aspect of this disclosure, the golf ball locator is a handheld unit having a volume of less than about 150 inches cubed and includes a transmitter, a transmit antenna, a receiver, a receive antenna and a processor coupled to the transmitter and to the receiver, and the handheld unit achieves a signal isolation, between a second harmonic of a transmitted signal from the transmitter and the receiver's received signal, of greater than about 130 to 160 dB. Other aspects are also described.

A circuit and method for providing an auto-off capability for a wireless transmitter, of a type having an audio plug which mates with the output jack of an audio source. The portable transmitter modulates signals from a baseband signal source onto a carrier and transmits the RF carrier to a receiver. The auto-off capability is provided to prolong battery life and eliminate the transmission of unmodulated RF carriers. The auto-off capability comprises turning power off to the transmitter circuit when baseband input signal is absent for more than a predetermined amount of time, and immediately turning on the transmitter circuit when baseband signal is present.

Circuit and method for providing an auto-off capability for a wireless transmitter

A headphone receiver apparatus for use with low power transmitters includes a pair of headphone speaker enclosures connected by a headband. An antenna element in the form of a spring steel band or a plastic cable/antenna band where one of the conductors is utilized as the antenna is configured generally concentric with but offset from the headband and the user's head by at least 0.5 inches over at least some length of the antenna. Low-noise performance is improved by a low noise amplifier incorporated before the receiver IC, and a bandpass filter interposed between the low noise amplifier and the receiver IC. A base-loading inductor is used to tune the antenna element to resonance, with or without capacative end-loading. Lumped inductors, ferrite beads, or a parallel resonant LC circuit may be used to isolate the shield conductor at RF frequencies, and/or to reduce the loading of the other conductors.

Headphone receiver apparatus for use with low power transmitters

A circuit (FIGS.A-D) and method of providing an auto-on and/or auto-off capability for an audio device, of a type having an audio plug () which mates with the output jack of an audio source. The portable transmitter () modulates audio signals from the audio source onto a carrier and transmits them to a receiver. The auto-on and auto-off capability is provided to prolong battery life and degradation of the transmitter circuit and comprises pinching off a FET (Q) when the circuit is in an 'off' state. This occurs when a pre-determined threshold in a capacitor is reached by not discharging that capacitor. The capacitor (C) is discharged by dropping a comparator input below a pre-determined threshold limit when presented with an audio peak and wherein the drop in value causes the comparator output to go low, causing the capacitor to discharge and causing the FET (Q) to supply power to the regulator.
