Abstract: A modular industrial transmitter includes a communication module and a sensor module. The communication module is configured to communicate with a remote device and has a common interface configured to couple to a plurality of different types of sensor modules. The sensor module is coupled to the common interface of the communication module. Physical coupling of the communication module to the sensor module is performed tool-lessly.

Abstract: The handle of the device includes several segments joined by connectors which permit disassembly and use of certain segments as individual handles. An elastic cord terminates in securement to certain of said segments and passes through a loop which serves to anchor the cord to a stationary object. The loop is formed with an enlarged portion to permit removable securement of the loop between a door and door jamb. The loop may also be placed about a user's foot during certain exercises. The connectors may have a castellated exterior for gripping purposes.
