Title: Method for multilevel dram sensing
Inventor: BIRK GERSHOM
IPC: G11C11/56
Filed: 1997-09-30
Abstract: A method for performing a sense and restore operation in a multilevel DRAM is described. The method describes the selective enabling of the sense amplifiers to operate at predetermined sensing thresholds. The multilevel DRAM stores two bits per cell using a four-voltage-level-per-cell system. Folded bitlines are divided into sub- bitlines each having dedicated sense amplifiers. The sense amplifiers are selectively enabled to operate at predetermined sensing thresholds to thereby greatly simplify the sense and restore operations. The circuit has standard CMOS bitline sense amplifier transistors connected thereto with pull down transistors that may be selectively enabled by switch signals. The length and width of these pull down transistors are varied to thereby effect the switching threshold of the sense amplifier.

Title: Method for installing a wireless network
Inventor: MELNIK GEORGE A
IPC: H04L29/12
Filed: 1997-08-08
Abstract: A method for installing a wireless network, which includes the steps of physically installing a plurality of nodes in respective different locations in a building, and using a wireless installation device to program a respective address into the nodes. The wireless installation device may also be used to program one or more default settings into the nodes, to verify operation of the nodes, and to dump information regarding the physical location and associated address of the nodes to a building computer. The wireless programming of the nodes is preferably accomplished using a software "handshaking" procedure which ensures that the address and default setting data is only loaded into the node currently being programmed, and not inadvertently into one or more other nearby nodes. In this connection, an iterative power reduction scheme can be utilized to prevent multiple nodes from being inadvertently assigned the same address.
