Title: Method for adjusting a transmission characteristic of an electronic circuit
Inventor: LUDI CHRISTOPH
IPC: A61B5/12
Filed: 2001-09-25
Granted: 2010-11-16
Abstract: In the method for the adjusting of a transmission characteristic of an electronic circuit, for example, in a hearing aid (1), a computer (2) with a monitor screen (3) and a mouse (4) are made ready. The hearing aid (1) to be adjusted is connected with the computer (2).  The current operating parameters of the hearing aid (1) are transmitted to the computer (2). The computer (2) from the operating parameters calculates the current transmission characteristic and represents this on the monitor screen (3) as a three-dimensional graphic diagram. The acoustics specialist with the help of the mouse (3) selects a point of a segment of the graphic diagram and modifies the graphically depicted transmission characteristic by moving the mouse (4). As a result of this, also the current operating parameters are modified. From these, a new current transmission characteristic is calculated and represented on the monitor screen (3) as a three--dimensional graphic diagram. This adaptation process is repeated for as long as required, until the current transmission characteristic coincides with the desired response.  Once this has been achieved, the current operating parameters are transmitted from the computer (2) to the hearing aid (1) and there stored in memory. This method is more intuitive, more graphically vivid and more easily handled than those known up until now, where only two-dimensional representations of the transmission characteristic are utilised. The method enables a more effective adjustment of the transmission characteristic and, in the case of hearing aids, a better hearing.

Abstract: Improvements in cast metal sideframes and bolsters for railway trucks are disclosed, along with improvements in the processes of casting such products and the cores used in the casting process. In one aspect, the cores are consolidated to provide two one-piece end cores, a one-piece center core, and a bottom center core for the sideframe and two one-piece end cores and a center core for the bolster. The consolidated cores may include cores to define various bolt holes. In another aspect, various cores may be made with step joints for an interlocking support without weight-supporting chaplets. In another aspect, a locator boss may be formed on one or more of the cores for proper positioning of the core on the drag mold. Other improvements disclosed include providing a radial draft on the casting surrounding a bolt hole at a core parting or joint line so that nuts and washers may be evenly loaded. In the bolster interior, ribs may be straightened. In another aspect, core prints are used to support the cores on the drag mold surface. The core prints are connected to the core body through necks or bridges that define holes in the cast metal piece. The juncture of the core print and drag mold are spaced from a perimeter of the neck so that any metal fin formed at this juncture is on the exterior of the casting.

Title: Systems and methods for determining, collecting, and using geographic locations of internet users
Inventor: LUTCH BENJAMIN
IPC: G06F7/00
Filed: 2000-05-02
Granted: 2009-12-01
Abstract: A method of determining a geographic location of an Internet user involves deter-mining if the host is on-line, determining ownership of the host name, and then deter-mining the route taken in delivering packets to the user. Based on the detected route, the method proceeds with determining the geo-graphic route based on the host locations and then assigning a confidence level to the as-signed location. A system collects the geo-graphic information and allows web sites or other entities to request the geographic loca-tion of their visitors. The database of geo-graphic locations may be stored in a central location or, alternatively, may be at least par-tially located at the web site. With this infor-mation, web sites can target content, adver-tising, or route traffic depending upon the ge-ographic locations of their visitors. Through web site requests for geographic information, a central database tracks an Internet user's traffic on the Internet whereby a profile can be generated. In addition to this profile, the central database can store visitor's prefer-ences as to what content should be delivered to an IP address, the available interface, and the network speed associated with that IP ad-dress.

Abstract: A method and apparatus for supervising a dedicated control channel when in the discontinuous transmission mode. The mobile station (4) monitors the frames it receives from a base station (2) and maintains a counter of bad, good, and empty frames, referred to as COUNT1, COUNT2, COUNT3, respectively. If a received frame is a good frame, COUNT1 is reset to zero and COUNT2 is incremented. If the received frame is a bad frame, COUNT1 is incremented and COUNT2 is reset to zero. If the received frame is an empty frame, COUNT1 and COUNT2 are unchanged but COUNT3 is incremented. A transmitter coupled to the mobile station is enabled or disabled depending upon which, if any, of the COUNTs reaches or exceeds a designated threshold value.

Abstract: A helm apparatus for a marine craft or other vehicle having a steered member such as a rudder includes a mechanically rotatable steering device and a sensor which senses angular movement of the steering device when the craft is steered. A communication link to the rudder enables the helm to monitor the rudder position. A bi-directional stop mechanism is actuated when the helm determines that the rudder position is beyond starboard or port hard-over thresholds, indicating that the rudder has reached a limit of travel. The helm can cause the stop mechanism to fully engage the steering device to stop further rotation of the steering device in a first rotational direction, corresponding to rotational movement towards said limit of travel. Rotational play is provided between the sensor and the stop mechanism, whereby the steering device can be rotated a limited amount, relative to the sensor, when the stop mechanism is fully engaged. The stop mechanism is released from engagement with the steering device when the sensor senses that the steering device is rotated, as permitted by said play, in a second rotational direction which is opposite the first rotational direction. Additionally, the same stop mechanism, or an optional steering effort mechanism, can be used to provide a dynamic steering effort, whereby the torque required to rotate the steering shaft is varied based on system inputs and configurations. The required torque is changed by fluctuations of the amount of friction between the steering effort mechanism and steering shaft, based on system inputs and configurations.
