Abstract: A portable multi-event reminder device includes a battery-powered electrical timer circuit that is programmable with respect to selecting at least two overlapping time periods, so as to generate prompts for at least two functionally related but time-independent events. A solitary two-state switch is the sole input device employed by a user to provide the desired timing programming. The timer circuit is configured to generate a first electrical reminder signal upon expiration of the first selected time period and to generate a second electrical reminder signal upon expiration of the second selected time period. The reminder signals activate one or more sensory alerts that generate human-perceivable alerts for prompting a user.

Abstract: A completely self-contained nerve stimulator/locator unit to be clamped on the syringe of a conventional syringe and injection needle assembly. The unit contains a power supply, a pulse generating circuit, a patient detector switch for automatically activating the generator when the injection needle touches the patient's body, a manually controlled current-adjusting potentiometer for permitting the physician to adjust the current values of the pulses, and an indicator for visually indicating the generation of each pulse. An LED/LCD digital display is also provided on the unit for displaying the current values of the pulses applied to the patient's body.
