Abstract: A zoned interactive control area (10) wherein an architectural space is divided in to a plurality of zones (16), each having its own sensor (22) and zone lights (18). In a normal operating mode (50) the sensors (22) are used to detect the presence of a person such that the zone lights (18) can be turned on and/or adjusted for light level. Each zone light (18) also has a light sensor (24) used, at least in part, for communication with the other zone lights (18), such that the light level can be adjusted not just in response to a presence in the respective zone (16) but also in response to presence in other zones (16). According to a security method (70) when the zone lights (18) are not in use for normal lighting (as when they are turned off) then if the sensors (22) detect the presence of an intruder the zone lights (18) flash to deter the intruder and also communicate the fact of the presence of the intruder to the other zone lights (18) via the light sensors (22).

Abstract: A method and apparatus to gain additional functionality of a microprocessor by adding an extended instruction set mode. In this mode, the result of executing an instruction may be changed without changing the instruction itself. In the extended instruction set mode, there is an increase to the number of bits of precision when executing the plus instruction. An additional bit position is added to the program counter register. When this bit is set, the microprocessor is in extended instruction set mode. In addition, a new one bit latch is provided. The latch may be changed only when the microprocessor is in extended instruction set mode. The latch is defined as holding a true carry bit. A significant bit of a register holding a sum is saved in the carry latch at the end of the plus instruction.

Abstract: A method and apparatus for serialization of a transmitted data stream and deserialization of data on a single die chip 105, including a plurality of processors 110 on a single chip 105. The processors on the chip 105 are connected by single drop busses 120 and act as individual processors with at least some dedicated memory 118. The method of serializing includes initialization of a register serializing a most significant bit from said register, moving all bits in the direction of the most significant bit, replacing the least significant bit with a value of zero, and continuing said serializing and moving steps are continued until a stopping condition is met. The method of deserialization of a data word includes initializing a register used for deserialization, deserializing a bit, positioning the bit in the least significant bit of the register, moving all bits in the direction of the most significant bit, and continuing the positioning and moving steps until a stopping condition is reached.
