The GUI includes recent history of changes in operating condition, and alarm indications such as poor health, along with the times of those events.

The invention provides an order-driven single-piece small-batch combined flow production method for a processing workshop, which has high intellectualization degree and strong practicability. In the method, a manufacturing system of the processing workshop is divided into a planning module, a scheduling module, a system database, an upper RFID reader-writer and an equipment control layer, wherein the planning control module, the scheduling module and an equipment control unit are all realized by Agent (intelligent agent) technology. All the parts of the manufacturing system are connected into a multi-Agent (intelligent agent) manufacturing system through a network and a communication protocol. Under normal conditions, the system carries out machining according to a preset operation working procedure through static scheduling; and when the system is abnormal, the system completes a processing task through dynamic scheduling. Accordingly, staff members can dynamically master production process information in real time. The production method can effectively improve processing efficiency and reduce production cost.

A method is disclosed for determining the operating condition of a medical pump based on data derived from a pressure sensor and a position sensor. The pressure sensor generates pressure data by sensing the force on the pumping element. The position sensor generates position data by tracking the pumping cycle and determining the position of the pumping element. The pump pressure data and pump position data are processed and the calculated results compared with a pre-determined threshold value to determine the operating condition of the pump. The three main types of operating conditions of concern are the following: normal condition, where liquid is present and no leaks exist in pumping chamber; leak condition, where liquid is present but a leak exists in the pumping chamber; and air stroke condition, where the chamber contains some air.

According to the invention, the security and driving comfort on driving road vehicles is increased by the fitting thereof with automatic systems for distance control and traffic separation. The operating properties of vehicles filled with such systems may be better adapted to traffic users merging into the lane thereof and the operating properties essentially better matched to those of a human vehicle driver, whereby an automatic traffic separation is carried out in which the position and speed of objects and traffic users are detected by a separation sensor. The vehicle is then subjected to a braking or acceleration, depending on said detected information. According to the invention, other information relating to the road layout from a navigation system or other data-bank containing road layout data is accessed, such that when the above information indicates that a detected traffic user under normal conditions is expected to merge into the lane of the road vehicle comprising said system, the driving properties of said road vehicle are matched to those of the detected traffic user.

An autonomous transport system is disclosed, formed by four main subsystems: a channel subsystem; a vehicle subsystem; a wheel guide subsystem and central control station subsystem. The system is designed for the transportation of people or goods, to be used in tall buildings and in small and large scale urban environments. It comprises unitary vehicles that may move in different directions: horizontal, steeply sloped and also vertical tracks, thanks to novel traction wheel assemblies that roll on carefully designed wheel tracks. The system's cabin maintains the horizontal level / position regardless of the changes of track direction or slanting thanks to pendulum based automatic level control and may rotate up to 180° under normal conditions and even a full 360° turn respect to the wheel assembly in space restricted positions. The cabin is mounted on a cantilever, thereby displacing its center of gravity respect of the wheel guides. Thus, a lever action is established, which presses the wheels against the wheel tracks and therefore enough frictional resistance is obtained so as to avoid wheel slippage on the wheel tracks. The vehicles are moved by non-polluting, electric drives that move and stop them with high energy savings. The vehicle runways are designed taking in account safety features against fire hazards. Several vehicles may be used at the same time and on the same track and may run individually or in groups, conforming a train. The system allows for vehicles to be parked in bypassed positions or else they may be disengaged from the convoy to be used individually.

Provided is a plastic bag including a live elastic strip that, in the elastic strip's normal condition, contracts thereby constricting an opening of the bag to assist in retaining the bag to an object. The elastic strip includes a first region that is continuously attached to a sidewall of the bag between a first side edge and a second side edge of the bag and a second region that remains unattached to the sidewall. The attached region does not contract but instead forces the portion of the sidewall to which it is attached to pucker into a serpentine path. The unattached region does contract causing the portion of the sidewall to which it is adjacent to bunch together. Also provided is a method for manufacturing a plastic bag that involves stretching a live elastic tape and continuously attaching a region of the stretched tape to a web of plastic material.

The invention is related to compositions which can be used as dermal formulations for supporting the skin to restore normal conditions in case of e.g. irritated skin, or to support medical therapy of skin with atopic dermatitis symptoms, atopic dermatitis, psoriasis or related diseases (e.g. accompanied by distorted barrier function of the skin and microbial load). The compositions of the invention can be used for dermo-cosmetic products but also for pharmaceutical / -medical products, depending on the composition and the additional actives incorporated (cosmetic actives or drugs). The invention is based on the synergistic effect of metallic particles, in particular silver particles (such as microsilver, nanosilver) and lipid particles (lipid nanoparticles or lipid microparticles). As alternatives to silver particles, other metallic particles (e.g. zinc, copper) or nanocrystalline actives can be incorporated (e.g. replacing the anti-oxidative silver by anti-oxidative nanocrystals of plant molecules such as hesperitin). This leads to combinations of lipid particles with nanocrystals for dermal use.

Thus, the human face expression recognition effects, the accuracy and the reliability can be promoted effectively.

In a cluster that is composed of two computer nodes and has no common storage, mutual aliveness is monitored over networks. However, this is insufficient because a party node may be wrongly determined as inactive. If failover is performed according to wrong determination, the counterpart may be restored to a normal condition after the failover, so that both the two computers may operate as master. The two nodes to constitute the cluster and other computers to communicate with the cluster are connected by switches that can disable ports to which the computers are connected. A network control program that controls the switches changes the legality of use of ports to which the nodes are connected, synchronously with node failover.

The main functionality is retaining the convenience of the press button operation while maintaining ruggedness and endurance of the product using such technique.

Dynamic thresholds statistically derived are used to define normal conditions at a specific site in an electric power distribution system. High and low and / or caution and alarm thresholds for various parameters are generated as multiples of the standard deviation of the long-term average of measured values calculated from samples gathered over repetitive intervals, such as ten minutes. Weekly averages are used until sufficient data has been gathered to maintain a running one year average.

The invention relates to an automatic surveillance system whereby characteristic data are first determined from a section of a signal (an instantaneous video image) using an automatic image analysis. This data is then stored temporarily or permanently with a time tag, so that it can be compared statistically with certain other time references. This statistical comparison enables the inventive surveillance system to identify abnormal situations and to selectively bring them to the attention of the surveillance officer. The invention is characterized in that the system itself identifies which situations are abnormal and require closer examination. It is not necessary to specify in advance what constitutes abnormal in a given surveillance situation, since after a certain period of running, the system itself will have collected the data corresponding to a normal situation.

A carrier phase-based relative positioning apparatus comprises a plurality of antennas of which at least one is installed on a mobile unit. The apparatus determines the position of each antenna other than one antenna used as a reference antenna relative to the reference antenna by receiving radio signals transmitted from a plurality of position-fixing satellites with the multiple antennas, observing a single difference phase or a double difference phase, and calculating an integer ambiguity of the single difference phase or the double difference phase. The apparatus judges that the integer ambiguity has been incorrectly determined if the position of any of the antennas relative to the reference antenna (or the angle of a flat plane formed by those two antennas) falls out of a preset range in which the relative position (the angle of the flat plane) falls under normal conditions.

An automated decision engine is utilized to screen incoming alarms using a knowledge-base of decision rules. The decision rules are updated with the assistance of a data mining engine that analyzes historical data. “Normal” alarm events, sequences, or patterns generated by sensors under conditions not associated with unusual occurrences (such as intrusion attacks) are characterized and these characterizations are used to contrast normal conditions from abnormal conditions. By identifying frequent occurrences and characterizing them as “normal” it is possible to easily identify anomalies which would indicate a probable improper occurrence. This provides very accurate screening capability based on actual event data.

A method and framework are described for detecting changes in a multivariate data stream. A training set is formed by sampling time windows in a data stream containing data reflecting normal conditions. A histogram is created to summarize each window of data, and data within the histograms are clustered to form test distribution representatives to minimize the bulk of training data. Test data is then summarized using histograms representing time windows of data and data within the test histograms are clustered. The test histograms are compared to the training histograms using nearest neighbor techniques on the clustered data. Distances from the test histograms to the test distribution representatives are compared to a threshold to identify anomalies.

The system is designed to reduce fuel consumption and air pollution while maintaining auxiliary systems in function and the cabin temperature at an acceptable level when the engine is stopped. This system may be integrated aboard internal combustion engine vehicles that have important idling periods in normal conditions. Such systems can either be implemented as retrofit kits or during a vehicle's manufacturing, directly by the original equipment manufacturer (OEM).

Instead of alternatively utilizing only one fabric or the other fabric of a redundant pair, both fabrics simultaneously transmit duplicate information, such that each packet forwarding module (PFM) receives the output of both fabrics simultaneously. In real time, an internal optics module (IOM) analyzes each information chunk coming out of a working zero switch fabric; simultaneously examines a parallel output of a working one duplicate switch fabric; and compares on a chunk-by-chunk basis the validity of each and every chunk from both switch fabrics. The IOM does this by examining forward error correction (FEC) check symbols encapsulated into each chunk. FEC check symbols allow correcting a predetermined number of bit errors within a chunk. If the chunk cannot be corrected, then the IOM provides indication to all PFMs downstream that the chunk is defective. Under such conditions, the PFMs select a chunk from the non-defective switch fabric. Under error-free normal conditions, however, the PFMs select a chunk arbitrarily from a default switch fabric. In this way, each chunk in real time is selected from a non-defective source and is thus guaranteed to be error free. Accordingly, if a switch fabric fails, no information chunks are lost anywhere in the system.
