A memory structure, includes (a) active columns of polysilicon formed above a semiconductor substrate, each active column extending vertically from the substrate and including a first heavily doped region, a second heavily doped region, and one or more lightly doped regions each adjacent both the first and second heavily doped region, wherein the active columns are arranged in a two-dimensional array extending in second and third directions parallel to the planar surface of the semiconductor substrate; (b) charge-trapping material provided over one or more surfaces of each active column; and (c) conductors each extending lengthwise along the third direction. The active columns, the charge-trapping material and the conductors together form a plurality of thin film transistors, with each thin film transistor formed by one of the conductors, a portion of the lightly doped region of an active column, the charge-trapping material between the portion of the lightly doped region and the conductor, and the first and second heavily doped regions. The thin film transistors associated with each active column are organized into one or more vertical NOR strings.

A serial, dual piston high pressure fluid pumping system that overcomes the difficulties of gas in the fluid stream without the need for added mechanical valves or fluid paths. A bubble detection and recovery mechanism monitors compression and decompression volumes of the serially configured dual pump head pump, and the overall system delivery pressure. Bubble detection is effected by sensing a ratio of compression to decompression volume and determining if the ratio exceeds an empirical threshold that suggests the ratio of gas-to-liquid content of eluent or fluid in the system is beyond the pump's ability to accurately meter a solvent mixture. The magnitude of the ratio of compression to decompression volume indicates that either the intake stroke has a bubble or that the eluent has a higher-than-normal gas content. Once a bubble has been detected, recovery is effected by forcing the pump into a very high stroke volume with the compression and decompression stroke limits constrained to obtain the largest delivery stroke compression ratio that will expel a bubble or solvent that has detrimental quantities of gas.

Reductions in energy consumption and maintenance requirements for operating a wastewater treatment plant are achieved by controlling the operation of pumps at pump stations along a force main in a systematic fashion. The operation of the pumps is controlled to manage the flow of wastewater along the force main to minimize energy consumption, to eliminate sediment, to manage peak pressures encountered by smaller pumps and to avoid septic conditions.

A robot hand able to change the manner of holding an object while force applied from a plurality of finger mechanisms to the object is adjusted without using an auxiliary finger mechanism. When force F₃ is applied to object w from a certain finger mechanism 13 among the plurality of finger mechanisms 11 to 13 is changed, the operation of each finger mechanism is controlled such that a “contact” of each of the finger mechanisms 11 to 13 in the object w and an “application force vector” from each of the finger mechanisms 11 to 13 to the object w satisfy a “stable gripping condition”. The “stable gripping condition” is a condition in which (1) the sum of each of forces and moments applied from the plurality of finger mechanisms 11 to 13 to the object w becomes zero, and (2) a slip index fr becomes minimum.

Method and system for enhancing visual perception of augmented reality presentation. Location and line-of-sight (LOS) of user wearing see-through head-mounted display (HMD) is detected. A background environment viewed through HMD is determined based on detected location and LOS. Color-attribute(s) of background environment at background location corresponding to user LOS is determined and compared with color-attribute(s) of foreground supplementary image to be displayed on HMD overlaid onto background environment at background location. When an incompatibility condition is detected, visual parameter(s) of supplementary image is adjusted to minimize incompatibility. Color-attribute determination may use information obtained from users previously at background environment, and may be based on user perception resulting from interactions of: geographic location, time when background environment viewed, and user LOS. Supplementary image may be displayed at alternate background location determined according to non-color characteristic of supplementary image. Supplementary image may be displayed according to physical characteristics of HMD display screen.

Method and system for enhancing visual perception of augmented reality presentation. The location and line-of-sight (LOS) of a user wearing a see-through head-mounted display (HMD) is detected. A future background environment to be viewed by the user through the HMD is predicted based on at least the detected location and detected LOS. At least one color-attribute of the future background environment at a background location corresponding to a user LOS is predicted. The predicted color-attribute is compared with at least one color-attribute of an intended foreground supplementary image to be projected on the HMD overlaid onto the future background environment at the background location. When an incompatibility condition is detected, at least one visual parameter of the supplementary image is adjusted to minimize the incompatibility condition, and the supplementary image is projected on the HMD at the background location with the adjusted visual parameter.

An open coil resistance heater uses one or more standoffs to engage and support the generally straight or uncoiled run of bare or insulated wire that is part of the resistance wire of the heater. The standoff has slots, which are sized to engage the bare or insulated wires for support purposes, and is removably mountable to the heater frame for supporting the run of uncoiled wire.

An anti-skid brake control system for a multi-wheeled vehicle includes both a paired function and an individual function. The paired function controls the wheels of the vehicle in unison. The individual function controls the wheels of the vehicle individually. A paired/individual logic circuit alternatively activates and deactivates the paired function and the individual function. A method for controlling the skid of a vehicle utilizing a paired function and a individual function is also provided.

A shock and vibration system for an infant care transport system with an enclosed infant care device. The shock and vibration system utilizes multiple damping systems that create a floating patient support system that allows the infant care device to move in the various axes of motion instead of being rigidly mounted to the frame or sub-frame, or any substructure.

Polymers containing an acetal or ketal linkage and their use in lithographic photoresist compositions, particularly in chemical amplification photoresists, are provided. The polymer is prepared from at least one first olefinic monomer containing an acetal or ketal linkage, the acid-catalyzed cleavage of which renders the polymer soluble in aqueous base; and at least one second olefinic monomer selected from (i) an olefinic monomer containing a pendant fluorinated hydroxyalkyl group R^H, (ii) an olefinic monomer containing a pendant fluorinated alkylsulfonamide group R^S, and (iii) combinations thereof. The acetal or ketal linkage may be contained within an acid-cleavable substituent R^CL in the first olefinic monomer. A method for using the photoresist compositions containing these polymers in preparing a patterned substrate is also provided in which the polymer is rendered soluble in aqueous base at a temperature of less than about 100° C. by acid-catalyzed deprotection of pendent acetal- or ketal-protected carboxylic acid groups.

An enhanced telephony call waiting feature and apparatus is provided wherein identifying information related to a third party wishing to converse with a first party already communicating with a second party is provided to the first party during a mute condition in a manner that minimizes the time period of the mute condition. The method is fully compatible with existing services while allowing for new services. The method comprises the steps of the local switching office sending a call waiting tone having predetermined characteristics to the first party and its apparatus responding thereto by generating an acknowledgment signal. The apparatus then initiates a mute condition simultaneous with the ACK signal generation, or in response to detection of a carrier signal, or at some other time after exchange of the call waiting tone and/or the acknowledgment signal has occurred. Various methods are disclosed which initiate and terminate the mute condition in the apparatus of the first and second party to allow for the receipt, storage, and display of caller identifying data while minimizing the period of time the first and second party are muted from communicating. The first party may either accept or reject the waiting call in the conventional manner as based on the third party identifying information. Notch filters may be utilized to eliminate frequency components associated with an acknowledgement signal to maximize time available for conversation.
