Abstract: UE location determined by collecting and preprocessing signal data at a detector and sending extracted data to a remote locate server. The detector buffers samples from signals provided by receive channels, detects known reference signals from receive channels based on reference signal parameters, isolates symbols carrying the reference signal from frames, extracts data from symbols, and sends extracted data to locate server. The locate server receives the extracted data, estimates locate observables based on the extracted data and calculates the UE location based on the estimated locate observables, the reference signal parameters and the extracted data. The detector and/or the server may also generate correlation coefficients between reference signals carrying spectrum received from a serving cell and utilize the correlation coefficients to cancel a serving cell signal in symbols that include known in advance reference signals from the serving cell and one or more neighboring cells of the wireless system.

Abstract: A process for oligomerization of an olefinic compound for producing an oligomeric product is carried out in the presence of an activated catalyst, a non-metal oxygen containing additive and optionally a zinc compound. The oligomerization catalyst is an activated catalyst, which is provided by combining a source of chromium, a ligating compound, and a catalyst activator or combination of catalyst activators. The non-metal oxygen containing additive is present in an amount such that the ratio of the molar amount of the non-metal oxygen containing additive to the molar amount of chromium in the source of chromium per 106 g/g Cr productivity is between 0.01 and 400.

Abstract: A heat exchanger assembly includes a core having first and second header tanks covered by tank caps. A pair of core reinforcing members presenting terminal ends extend between the first and second header tanks. A least one tab and an opening for receiving the tab are used for connecting the core reinforcing members to the tank caps.

Abstract: A telephone accessory that is connected to a subscriber's telephone line as an extension, and monitors the line for the initiation of a call from any telephone set. The invention detects a call initiation by determining that a telephone set has seized the line without ring voltage being present immediately beforehand. If the first digit dialed by the subscriber is a “1”, the invention immediately dials the remainder of a long-distance access code, without the initial “1”, followed by a “1” which signifies a long distance number. This burst of dialed digits takes a short time, after which the subscriber continues to dial the area code and number as normal. The effect for the subscriber is to manually dial a normal long ditance nimber as 1+area code+number, while this invention takes advantage of the fact that long distance access codes begin with “1” and automatically inserts the desired code.
