A stair-climbing wheelchair has a pair of track assemblies that can be placed in an operative drive mode to propel the wheelchair along ascending and descending paths of travel relative to an obstacle such as a stairway, curb, or the like. Each track assembly includes a guide member with rollers at opposite ends thereof carrying an endless cleated belt. The guide member is arched between its end sections thereby permitting the endless belt to deflect upwardly between the rollers when the endless belt engages an obstacle such as a step, curb or the like. This permits a smooth gradual transition of the wheelchair onto and / or off the top step of a staircase. Preferably, each track assembly also includes an inclined tail section having a separate endless cleated belt. The track assemblies can also be utilized in connection with remote control and / or unmanned motorized vehicles.

In one example embodiment an implantable lens includes an anterior surface, a posterior surface and an outer edge surface separating the anterior and posterior surfaces. The anterior surface can include a corrective portion and a beveled portion. The beveled portion can be located between the corrective portion and the outer edge surface. The outer edge surface can have a first portion and a second portion, where the first portion abuts the posterior surface and the second portion, and where the second portion further abuts the beveled portion. The modified edge region provides a more gradual transition between the anterior and posterior surfaces.

A combination of noise suppression using a Bark band modified Weiner filter and linear noise reduction improves elimination of noise in a telephone. A detector for detecting long, non-speech intervals is coupled to the output of the noise suppresser and controls selection of noise suppression or noise reduction. A gain smoothing filter has a long time constant when noise reduction is used and provides a gradual transition from one level of gain to another. Comfort noise is smoothly inserted by updating the data for generating comfort noise only during detected long, non-speech intervals.

The present invention uses metallization termination techniques to reduce the electro-magnetic field scattering at the edges of metallized areas. The metallization termination techniques provide a gradual transition from high conductivity areas to high impedance areas. The mobile phone antenna illuminates the PCB allowing currents to flow on the PCB. When the currents reach edges of the PCB they flow through a region of increasingly high impedance without reflecting back or scattering.

A spiral cut transition member is disclosed for controlling the transition in stiffness of a catheter from a stiffer more pushable proximal section to a more flexible and trackable distal section and increasing kink resistance.

The transition member may be used in conjunction with any type of catheter including single-operator-exchange type catheters, over-the wire type catheters, and / or fixed-wire type catheters.

The handoff management system maximizes the communications capacity available from terrestrial air-to-ground cellular networks, while also integrating communications capabilities from satellite air-to-ground cellular networks and terrestrial cellular communications networks. The communications capacity is maximized by dynamically allocating communications from the aircraft over multiple communications channels to multiple cells of the terrestrial air-to-ground cellular network, and to satellite air-to-ground cellular networks and terrestrial mobile networks. This approach effectively provides an increase in the call handling capacity available to any aircraft and permits a gradual transition of communications from one cell to the next cell, rather than requiring an abrupt handover of all traffic from the aircraft from one cell to the next cell.

A prosthetic patellar component includes a base and a bearing element that includes first and second femoral engaging surfaces disposed between first and second (superior / inferior) edge surfaces. The edge surfaces are curved to provide a gradual transition from a posterior facing portion to a nearly vertical superior or inferior facing portion. Moreover, the inferior-superior dimension of the component is at least approximately 90% of the medial-lateral dimension. The relative height and gradually transitioning edges significantly reduce the likelihood of sudden posterior rotation during deep flexion movement. The edge surfaces extend from a substantially posterior facing portion proximate to the first and second femoral engaging surfaces and a substantially vertical facing portion proximate the base. The curved edge surfaces can include a plurality of adjacent medial-laterally extending surface portions having angular displacement relative to an adjacent surface portion of less than 30 degrees in the anterior-posterior direction.

The invention discloses a liquid-filled vibration isolator. The liquid-filled vibration isolator (A) has a first orifice channel (P1) providing communication between a pressure receiving chamber (f1) and a balancing chamber (f2). One of the pressure receiving chamber (f1) and the balancing chamber (f2) is communicated via a second orifice channel (P2) with an intermediate liquid chamber f3. The second orifice channel (P2) has a shorter distance or a larger cross-sectional area than the first orifice channel (P1). An elastic film member, such as a membrane (42), separates the intermediate liquid chamber (f3) and the other of the pressure receiving chamber (f1) and the balancing chamber (f2) from each other. A communicating hole (42a) of a predetermined size is formed in the elastic film member. An imaginary orifice channel combined from the two orifice channels (P1) and (P2) provides a high damping effect on input vibration of relatively low frequency. As the vibration frequency increases, a gradual transition is made to the damping characteristic of the second orifice channel (P2) only.

A controller in a video headend or other transmission element of a signal distribution system is operative to detect a condition in which unicast transmissions of a given content stream to a plurality of terminals meet a specified threshold. The controller starts a multicast transmission of the given content stream in response to the detected condition, and transitions at least one of the terminals to the multicast transmission. In one embodiment, the controller identifies at least one of the terminals as a terminal that will receive the multicast transmission of the given content stream in place of its unicast transmission prior to one or more of the other terminals receiving the multicast transmission. The controller stops the unicast transmission to the identified terminal if that unicast transmission has already been started, starts the multicast transmission, switches the identified terminal to the multicast transmission, and subsequently transitions one or more of the other terminals to the multicast transmission. The identified terminal may be a leading terminal or a trailing terminal.
