In some locations, such as airports, drivers that provide passenger transport must wait a significant distance away from the pickup location. To reduce the delay between a passenger requesting a ride and being picked up, drivers are pre-dispatched before being assigned to specific passengers. The demand for a future time period is predicted and the number of drivers that should be pre-dispatched to meet that demand is estimated. The estimated number of drivers is sent pre-dispatch instruction indicating they should leave the waiting area and head towards the pickup location.

Spread-spectrum technology, either direct sequence or frequency hopping, or a combination of the two, is used for transmitting audio signals one way and control signals two ways over an RF channel(s) to reduce interference with / from other RF transmissions and enabling use of multiple such systems in close proximity without requiring pre-selection of transmission frequencies. Alternatively, multiple channels with appended access codes may be used, wherein interference or loss of clear signal results in automatic switching to another channel. The control signals accompany the transmitted audio signal at some time in the transmission interval, or previous to the beginning of the transmission interval, and constitute a coded control message allowing a unique connection. In some cases the encoding keys may only occur at the beginning of the desired message, while in other cases the two-way control signals may continue throughout the interval of the message link.

A coffee machine with an integrated coffee grinder and a powder chute, which serves the purpose of feeding ground coffee from the coffee grinder to a movable brewing cylinder, has an inlet with a manually operated lid for already ground special coffee. A sensor detects the position of the lid. The detection signal of the sensor is passed on to a processor controlling the coffee machine, and the signal is used to differentiate between a normal operating mode and an operating mode for producing special coffee. If the lid is opened for a certain minimum time span, a subsequent coffee preparation cycle in the operating mode for producing special coffee is initialized. Since, to that end, no separate pre-selection is required any longer, the operation of the coffee machine is simplified and the susceptibility to problems is reduced.
