Abstract: A honeycomb device is provided for heat exchange between first and second fluids at distinguishable temperatures. The device includes first and second fluid intakes, first and second fluid exhausts, first and second capillary arrays, and first, second, third and fourth channels. The first and second fluid intakes respectively receive the first and second fluids. The first and second fluid exhausts respectively discharge the first and second fluids. Each first and second capillary in the arrays are disposed in checkerboard cross-section adjacent arrangement, and preferably have a rhombus cross-section. The first transition channel connects the first fluid intake to the first capillary array. The second transition channel connects the first capillary array to the first fluid exhaust. The third transition channel connects the second fluid intake to the second capillary array. The fourth transition channel connects the second capillary array to the second fluid exhaust.

Abstract: One embodiment of the present invention provides a computer system that implements a modular access point for clients on a wireless network. This modular access point provides the usual bridging functions to a wired network, such as an Ethernet or a Token Ring. In addition, the modular access point provides other services, such as a printer service, a facsimile service, or a firewall for connecting to a broadband connection. By providing these services within a modular access point, the present invention can reduce cost and can facilitate easier administration at the wireless network.
