20080315917 | Programmable computing array - Methods, devices, and systems for programmable computing arrays have been described. One or more embodiments include programming both a first and a second floating gate of a combined memory and logic element to one of at least two states, wherein programming the floating gates to one of the at least two states causes the combined memory and logic element to operate as a first logic gate type. One or more embodiments also include programming both the first and the second floating gates of the combined memory and logic element to another of the at least two states, wherein programming the floating gates to another of the at least two states causes the combined memory and logic element to operate as a second logic gate type, the second logic gate type being different from the first logic gate type. | 12-25-2008 |
20080316828 | Memory in logic cell - Methods, devices, and systems for a memory in logic cell are provided. One or more embodiments include using a cell structure having a first gate, a second gate, and a third gate, e.g., a control gate, a back gate, and a floating gate, as a memory in logic cell. The method includes programming the floating gate to a first state to cause the memory in logic cell to operate as a first logic gate type. The method further includes programming the floating gate to a second state to cause the memory in logic cell to operate as a second logic gate type. | 12-25-2008 |

20090016019 | AIRFLOW CONTROL AND DUST REMOVAL FOR ELECTRONIC SYSTEMS - Airflow control and dust removal systems and methods are disclosed. In one embodiment, a plurality of blade servers is mounted in a chassis. A blower generates airflow through the chassis. Air enters the chassis uniformly across the blade servers and flows in parallel through the servers. An airflow directing mechanism is provided for allowing airflow through a selected one of the blade servers while reducing or closing airflow to the other blade servers, to individually clean and remove dust from the selected blade server. The airflow directing mechanism may include a movable vane actuated by a rotary or linear solenoid to selectively block airflow ports of the servers. The vane may be held in a closed position, assisted by an electromagnet. The airflow directing mechanism may alternatively comprise a rolled shade having a pattern of openings. The position of the rolled shade may be controlled to align openings in the shade with airflow ports in the servers, to control which servers airflow may pass through. | 01-15-2009 |
20090021270 | CAPACITIVE DETECTION OF DUST ACCUMULATION IN A HEAT SINK - A system and method for electronically detecting the accumulation of dust within a computer system using a capacitive dust sensor. The dust detection system may be implemented on a smaller computer, such as an individual PC, or in a more expansive system, such as a rack-based server system (“rack system”) having multiple servers and other hardware devices. In one embodiment, each server in a rack system includes a capacitive sensor responsive to the accumulation of dust. The capacitive sensor may include one or more capacitive plates integral with a heatsink. As dust collects on the capacitive plates, the capacitance increases. When a capacitance setpoint is reached, indicating the dust has reached a critical level, an alert is generated. The alerts may be received by a management console for the attention of a system administrator. Each alert may contain the identity of the server generating the alert, so that the system administrator knows which server(s) are to be removed for cleaning. | 01-22-2009 |
20090214010 | Selectively-Expandable Speakerphone System and Method - According to one embodiment, a selectively-expandable speakerphone system allows one or more portable computers to automatically, wirelessly interface with a speakerphone console via an audio access point. A scheduling module initiates the conference call at a scheduled time, whereupon the wireless network interface of each portable computer is automatically switched to an SSID uniquely associated with the audio access point, for connecting to the speakerphone console. The audio signals generated by the laptop microphones are mixed with any audio signal generated by an optional microphone on the speakerphone console, and the mixed audio signals are transmitted over the telephone line. Incoming audio signals are passed to the speakerphone console and wirelessly transmitted to the portable computers for substantially simultaneous playback on the respective loudspeakers. | 08-27-2009 |
20090234995 | MOTHERBOARD DETECTION OF COMPUTER CHASSIS TYPE - A computer motherboard detects the form factor type of the chassis in which it is installed to permit tailoring functionality accordingly. | 09-17-2009 |
