## Abstract

A wrist worn muscle movement monitoring device includes a wrist strap; a sensor that responds to muscle movement at a wrist wearing the wrist strap; and monitoring circuitry connected to the sensor.

## Claims

### Claim 1

A wrist worn muscle movement monitoring device comprising:
a wrist strap;
a sensor that responds to muscle movement at a wrist wearing the wrist strap;
monitoring circuitry connected to the sensor; and
memory that stores sensor-based output of the circuitry.

### Claim 2 (depends on 1)

The wrist worn muscle movement monitoring device of claim 1, wherein the sensor comprises a piezo sensor.

### Claim 3 (depends on 1)

The wrist worn muscle movement monitoring device of claim 1, wherein the circuitry determines grip pressure of hand of the wrist based on sensor readings.

### Claim 4 (depends on 1)

The wrist worn muscle movement monitoring device of claim 1, wherein the sensor responds to a change in a circumference of the wrist.

### Claim 5 (depends on 1)

The wrist worn muscle movement monitoring device of claim 1, wherein the sensor generates sensor readings during a swing of a golf club held by a hand of the wrist.

### Claim 6 (depends on 1)

The wrist worn muscle movement monitoring device of claim 1, wherein the circuitry generates sensor-based grip pressure values storable to the memory.

### Claim 7 (depends on 1)

The wrist worn muscle movement monitoring device of claim 1, comprising an accelerometer operatively coupled to the circuitry.

### Claim 8 (depends on 7)

The wrist worn muscle movement monitoring device of claim 7, wherein the circuitry generates accelerometer-based speed values storable to the memory.

### Claim 9 (depends on 1)

The wrist worn muscle movement monitoring device of claim 1, wherein the circuitry generates a signal by comparing a sensor-based value to a benchmark value.

### Claim 10 (depends on 9)

The wrist worn muscle movement monitoring device of claim 9, wherein the circuitry generates the benchmark value.

### Claim 11 (depends on 1)

The wrist worn muscle movement monitoring device of claim 1, comprising a display.

### Claim 12 (depends on 11)

The wrist worn muscle movement monitoring device of claim 11, wherein the display renders sensor-based grip pressure values corresponding to an actual golf swing of a wearer of the wrist worn muscle movement monitoring device.

### Claim 13 (depends on 1)

The wrist worn muscle movement monitoring device of claim 1, wherein the sensor is carried by the wrist strap.

### Claim 14 (depends on 1)

The wrist worn muscle movement monitoring device of claim 1, wherein the circuitry comprises an analog to digital converter that converts analog signals of the sensor to digital data.

### Claim 15 (depends on 1)

The wrist worn muscle movement monitoring device of claim 1, wherein the sensor is carried by the wrist strap and wherein the circuitry comprises an analog to digital converter that converts analog signals of the sensor to digital data.
