摘要： A data telemetering system includes a plurality of remote transmitter units connected via an alternating current power supply mains to a central receiver. Each cycle of the line voltage is divided into a plurality of time slots, and each transmitter transmits its data in a separate time slot assigned to it. The data is binary multi-bit digital data, and one bit is transmitted by each transmitter in its assigned time slot during each cycle of the line voltage.

摘要： Outbound signals carried over an electric power network are detected and crosstalk is rejected by sampling the waveform in three segments of each cycle. In the first segment valid signals are always absent. Valid signals appear at the same time in both the second and third segments. Sample waveform values from alternate half cycles are compared to detect differences indicative of outbound signal information. The energy in each of the three segments is compared with an energy threshold for that segment and a cycle under test is rejected when the energy in the first segment exceeds the threshold for that first segment. A cycle under test is also rejected if the energy in the third segment greatly exceeds the energy in the second segment. Signal detection thresholds for both signal strength and energy in the segments are set recursively using actual samples acquired at the outbound detection site. These thresholds are sensitive to dynamic network changes.

摘要： The switching circuit couples an appliance (1) to a power main (LN) via remotely controllable switching means (2) and is operable to change the state of the switching means (2) in response to a manual double switching of the appliance power switch so that the appliance can be manually switched ON after it has been remotely switched OFF.A capacitor (CAP1) generates from the mains voltage an alternating current signal of a phase differing from that of the mains voltage by an amount dependent on the external impedance across the output. The switching circuit monitors this phase difference and changes the state of the switching means (2) if it detects two phase difference changes exceeding a predetermined value in opposite senses within a predetermined time period, this being indicative of a manual double switching of the appliance power switch.The switching circuit does not operate spuriously for thermostatically controlled appliances nor in response to noise spikes.

摘要： Control signals are transmitted through a.c. mains supply lines to control operation of electrical equipment powered from the supply lines. A near short-circuit condition is introduced across the a.c. mains supply lines, for example, by firing a thyristor connected in series with a fuse across the supply lines, for the final portion of positive half cycles of the mains supply voltage, thus holding the voltage to a near zero value for this length of time. A receiver coupled to the mains supply lines includes a zero crossing detector circuit which responds to the near zero voltage conditions across the supply lines to perform a particular control operation on an associated appliance connected to the receiver. Different control operations may be effected by defining the control signals over a group of half cycles of the a.c. supply mains and selecting one or more half cycles of the group during which the supply voltage is reduced to the near zero level, thereby producing a sequence of selected and non-selected half cycles within the group so that by changing the sequence the particular control operation can be changed accordingly.
