Appl. No.:

09/729473

Inventors:

Jason Kim - San Diego CA 92122

International Classification:

C02F 124

US Classification:

210703, 210905, 210776, 210169, 2104162, 119264

Abstract:

A protein skimmer for removal of protein contaminates from protein contaminated water. An injector is used for spraying protein contaminated water into a water bubble chamber. The spraying motion causes bubble generation in the water bubble chamber. Contaminates in the water attach themselves to the bubbles and rise to the surface of the water as foam. A hollow foam riser is attached to the top of the water bubble chamber and provides an exit pathway for the contaminated foam. As foam is generated, it rises through the foam riser and carries with it contaminates. A foam collection cup is attached to the top of the foam riser and collects the contaminated foam. Consequently, the water left behind in the mixing chamber is substantially more pure. The substantially more pure water exits the mixing chamber through a purified water exit aperture.

Inventors:

Jason J. Kim - Lafayette CA

International Classification:

H01J 114

US Classification:

313346R

Abstract:

Disclosed is a method and apparatus for producing a high electron beam current having a low energy spread at a high brightness of the beam and a uniform intensity distribution. The electron beam is extracted from an emission current which consists of used emission current and unused emission current. The used emission current has a uniform intensity distribution. The apparatus produces a negligibly small unused emission current by using both a frustum shaped cathode and a multi-electrode. The cathode comprises a thermoelectron emissive material having a low work function and one or more thin layers which cover the side surface of the cathode. A material of the outermost thin layer has a high work function. The multi-electrode consists of the cathode, a first grid electrode, a second grid electrode and an anode electrode. The used emission current is generated from the top surface of the cathode.

International Classification:

H03K 1712

US Classification:

361 93

Abstract:

A current limiting circuit and technique is provided for preventing excessive current supplied to a circuit and for providing self-recovery characteristics thereto. The current limiting circuit includes an input for receiving a supply voltage for supplying power to the monitored circuit and an output for providing the power to the desired circuit being monitored. The circuit employs a drive transistor having a source connected to the input and a drain connected to the output. The drive transistor further includes a gate for receiving a control signal. A current mirror circuit is provided for sensing a current overload and adjusting the control signal to indicate the amount of current drawn. During normal current draw, the circuit provides the supply voltage as the output. When excessive current draw is detected, the drive transistor is turned off and the output current is thereby cut off.

International Classification:

G06F 1202

US Classification:

395413

Abstract:

A virtual addressing buffer circuit has improved address mapping and control flexibility for improved physical resource management and a unique opportunity for forward-compatible system design. The virtual addressing buffer formats the output address utilizing a format register as a combination of the new address bits and the original input address bits. The ability to format the output address enables the user to replace certain address bits without requiring that the entire address be replaced. The virtual addressing buffer controls the output of several command signals to external circuits to indicate how the system should respond to the address output from the virtual addressing buffer. The command signals are controlled by a command register and are output from the virtual addressing buffer only when an address match has been verified. The virtual addressing buffer circuit filters out certain bits of an input address as indicated by a filter register before it verifies that the input address matches a stored address.

International Classification:

G06F 1200

US Classification:

711167

Abstract:

A rule-based DRAM controller asserts memory access and control signals (including the CAS, RAS, WE, and address data signals) based upon pre-specified control rules. Certain pre-specified rules, or conditions, are used by the DRAM controller to determine the timing and sequence of the memory accessing and control signals output by the DRAM controller. The control rules for asserting the various memory accessing signals are advantageously implemented as logic within the DRAM controller, while the conditions and qualification for the control rules are provided from various monitoring signals and independently operating timing modules which keep track of the DRAM and controller states. Based upon these rules and conditions, the request inputs to the DRAM controller are interpreted to provide optimum access speed to the DRAM.

Abstract:

A method and apparatus using a virtual addressing buffer circuit afford address mapping and control flexibility to provide a unique opportunity for device emulation and software debugging. The method permits the emulation of a device which is physically not present in a CPU controlled system utilizing a virtual addressing buffer circuit. The method includes the step of storing a match address which corresponds to an address location of the device. The virtual addressing buffer intercepts an address request from a CPU for the address location of the device. Bits of the requested address which are not relevant to a determination of whether the requested address matches the match address are filtered out to produce a filtered request address. The filtered request address is compared with the match address, and a match indicator is activated when the filtered requested address matches the match address. A terminate command is provided to a bus controller connected to the CPU and a local memory when the match indicator is active.
