Abstract: An automated order fulfillment system and mobile robot are disclosed, where the mobile robot includes a compliant drive for moving between levels of a multilevel storage structure. In one example, the compliant drive comprises a drive shaft having splines configured to provide rotational play that prevents jamming of a vertical drive gear on the end of the shaft with a rack in a vertical track.

Abstract: A method includes receiving data characterizing time-dependent lateral vibration of a shaft of a machine, the lateral vibration indicative of motion of at least a portion of the shaft perpendicular to a first direction. The lateral vibration is detected by a first sensor located at a first predetermined location on the shaft. The method further includes, receiving data characterizing time-dependent torsional vibration of the shaft, the torsional vibration indicative of rotation of the shaft around the first direction. The torsional vibration is detected by a second sensor located at a second predetermined location on the shaft. The method also includes calculating a coherence of the data characterizing time-dependent lateral vibration and the data characterizing time-dependent torsional vibration.

Abstract: Methods and systems for identifying and presenting information are described. Search results are received from a search engine. An entity associated with a networked site is selected using a selection criterion. A determination is made as to whether the listing includes a link to the networked site or includes the link to the networked site at a list position that fails to satisfy a first criterion. After determining that the link to the site associated with the entity is not included in the search result listing, or that the link to the site associated with the entity is not at a position in the search result listing that satisfies the first criterion, the search listing is modified by causing the link to the site associated with the entity to appear in a first position in the search listing. The modified search listing is displayed on a user terminal.

Abstract: Methods and systems are described for processing and display content. Web page data for a first web page is received from a remote system, wherein the web page is to be displayed on a terminal associated with a user. An automatic identification is performed of a first content in the first web page data. A user-defined profile is accessed. A second content is automatically selected based at least in part on the user profile. The first content is replaced with the second content so that if the first web page is displayed on the terminal associated with the user, the second content is displayed and the first content is not displayed.

Abstract: During elevator modernization, a cross-dispatching system receives hall calls and assigns each hall call to either a group of existing elevator car controllers or a group of new elevator car controllers. The cross-dispatching system creates an inter group relative system response (iRSR) value for the hall call for both the existing group of elevators and the new group of elevators, based upon information from each group such as car location, in-service status, load, and direction. If the group assigned the hall call does not answer the call within a redispatch time period, the cross-dispatching system again calculates the iRSR for each group and reassigns the hall call.

Abstract: A method for monitoring a condition of at least one valve positioned with respect to at least one of a first chamber and a second chamber of a reciprocating compressor is provided. The method includes establishing a compressor operation cycle including a valve opening event, a valve closing event and/or a rod reversal event. A crank angle is determined at each of the valve opening event, the valve closing event and/or the rod reversal event during the compressor operation cycle using at least one of a static pressure input and a machine speed input. The method further include diagnosing a valve leak condition during the compressor operation cycle at the valve closing event, wherein the at least one valve is closed.

Abstract: A sinusoidal modulated signal and noise are applied to a system consisting of two oscillators of the so-called General Type, which can be, but are not limited to, the Van der Pol type, Rotator type, Tracking Force type, Linear type, or any other type of oscillator. The two oscillators in the system can also be of different types. The General Type oscillators are tuned for specific frequencies of the incoming sinusoidal modulated signal. The process of adjusting of oscillators to an incoming signal is known as Dynamic Synchronization. During the transitional period, because the noise is random, the noise pushes the frequencies of the General Type oscillators in opposite directions over time and thus self-eliminates its impact on such oscillators. The resulting signal is much less noisy, i.e., clarified, so that the sinusoidal modulated signal can be further evaluated by, for example, extracting and further analyzing its spectral peaks.
