摘要:
A device, worn on a part of the human body, which alerts the wearer when that body part deviates a set angular amount from true vertical, comprising a housing containing an attitude responsive switch which controls an electrical circuit. When the switch is positioned or rotated beyond a set angle, the circuit is completed and a battery activates a buzzer. The device is adjustable by rotation of the housing such that the amount of allowable deviation can be increased or decreased.

Methods, systems, and computer readable storage media are provided for operating a vehicle including an engine that may be automatically shutdown in response to AESS conditions. In one example, the method comprises, determining an AESS emission credit corresponding to an amount of AESS operation; and adjusting an engine operating parameter based on the determined AESS emission credit. Further, in another example, the method comprises retarding injection timing in response to manifold air temperature, wherein an amount of retard is adjusted responsive to an amount of AESS operation.

Dynamic health assessment systems and methods related to monitoring fuel flow control are provided. In one embodiment, a method for controlling a system having an engine is provided. The method includes during a no-load condition of the engine, stopping fuel injection by a plurality of fuel injectors of the engine, closing a valve that is operable to control fuel flow to a fuel pump that pumps fuel to a common fuel rail, and setting a degradation condition in response to a fuel rail pressure decay rate of a fuel pressure in the common fuel rail being greater than a decay threshold after a first designated duration.

The present invention addresses the need to improve the yields of viral vectors when grown in cell culture systems. In particular, it has been demonstrated that for adenovirus, the use of low-medium perfusion rates in an attached cell culture system provides for improved yields. In other embodiments, the inventors have shown that there is improved Ad-p53 production with cells grown in serum-free conditions, and in particular in serum-free suspension culture. Also important to the increase of yields is the use of detergent lysis. Combination of these aspects of the invention permits purification of virus by a single chromatography step that results in purified virus of the same quality as preparations from double CsCl banding using an ultracentrifuge.

An aircraft communications system includes a wireless local area network (LAN) access point positioned within the aircraft that receives and transmits wireless communications to and from at least one portable wireless communications device. A control panel is operatively connected to the wireless LAN access point and positioned within the flight deck of the aircraft. A communications transceiver is operative with the control panel and wireless LAN access point and operative for receiving and transmitting a communications signal between the wireless LAN access point and a ground-based transceiver. Communications between the portable wireless communications device and ground-based transceiver can be controlled from the flight deck using the control panel in one non-limiting example.

A circuit is provided for over-driving a super-luminescent light emitting diode having a maximum forward continuous current rating. A power supply provides a pulse width modulated signal to an analog memory connected to the power supply and a pulse generator. The pulse generator includes a window comparator engaged with the analog memory, and is responsive to a portion of the pulse width modulated signal. A power driver that is controlled by the output of the pulse generator, is operably connected with the super-luminescent light emitting diode and with the power supply so as to energize the super-luminescent light emitting diode with a current that is above the maximum forward continuous current rating by between two and ten times that rated current. A signal is also provided along with a method of over-driving a super-luminescent light emitting diode. An inverter and timer are coupled to the pulse generator and an array of light emitting diodes that operate at time intervals determined by the timer that are wholly distinct from time intervals when the at least one super-luminescent light emitting diode is over-driven.
