When an entity (such as a customer using a communication device 131, 141, 151 . . . ) attempts to communicate with a target (such as an employee), an arrangement indicates to the customer, “status” information describing at least the employee's present and future ability to communicate with the entity (such as by returning his call). At least one sensing device 111-119 is configured to provide sensing information concerning the target employee's status in response to an action of the target employee with respect to the sensing device. A monitoring server 102 is configured to receive the sensing information and to govern communication to the entity (customer) of the target's “status.” In one implementation, a particular sensing device (such as a cash register 111, computer terminal 112, or time clock 113) is configured to perform both (A) a primary function that is not related to providing the sensing information, and (B) the secondary function of providing the sensing information. In this implementation, the particular sensing device provides the sensing information in response to the person's ordinary use of the particular sensing device as he goes about his job (performing the particular sensing device's primary function), so that the person does not have to explicitly perform any purely presence-related action in order to cause the particular sensing device to communicate the sensing information.

A spa control system designed to reduce maintenance cost by providing modular construction for major control functions, with built-in diagnostic capabilities for isolating defective spa components. Multi-colored LEDs on the spaside panel constantly report the status of each component of the spa as well as the status of the functional modules themselves. Each time a component is activated, measurements of operational parameters, such as load currents, are instantly made and evaluated so that the proper LED color can be presented at the spaside. Since major functions such as audio, LED control, wireless, and spa logic are separated into removable modules, repair of the control system requires less time and less skilled personnel. Other design improvements, such as direct monitoring of heater element temperature and the purging of pumps on an as required-basis, enhance the spa's overall reliability and thus reduce the need for maintenance.

Proposed is a light module (110) comprising at least two primary light sources (111,112,113) capable of emitting a primary color light. This allows the light module to emit light having intensity (Y) and color coordinates (x,y) through additive color mixing of the constituent primary colors. The light module further comprises an modulator (115) capable of modulating the primary light sources enabling embedment of data in the light emitted. The modulator (115) is arranged to modulate the color coordinates of the light emitted for embedding the data.
