Title: Seed tube for seed metering apparatus
Inventor: JOHNSON CHAD M
IPC: A01C7/20
Filed: 1999-01-25
Abstract: A seed tube for an agricultural implement having a seed metering mechanism for uniformly dispensing seeds. The seed tube defined an enclosed curved seed pathway extending between opposite ends of the tube. To promote control over the seeds passing through the tube, the tube has a smooth but decreasing cross-sectional configuration between the ingress and egress ends of the tube. The tube generally includes a front wall, a rear wall and a pair of side walls. The front wall is generally separated into an upper and lower portion. An opening in the front wall, which is provided to receive a monitoring device, is associated with the lower front wall portion In addition, the lower front wall portion is stepped forward relative to the upper front wall portion. The enclosed seed pathway further includes a narrowed front edge extending in an upward direction from the egress end of the tube along some section of the front wall. The narrowed front edge enhances-control over the seeds such that individual seeds passing through the tube and deposited to the ground have equidistant spacings between the seeds on the ground. The stepped forward arrangement for the lower front wall portion also allows a monitoring device to be used without disrupting the flow of seeds in the seed tube.

Title: Motion transmitting apparatus for use with an automotive vehicle multi-functional apparatus
Inventor: DAN PETRE
IPC: B60S1/04
Filed: 1998-04-03
Abstract: A motion transmitting apparatus for use with an automotive vehicle multi-functional apparatus (51) includes an electromagnetic device (71), a rotatable member (73), an interface surface, a shaft and an intermittent motion mechanism (75, 77, 79). Another aspect of the present invention provides rotation of the rotatable member within a first positional range to cause the interface surface to contact and move an arm (505) of the intermittent motion mechanism (77) from a first actuation position to a second actuation position.  The arm subsequently moves past the actuation positions as to allow the interface surface to disengage the intermittent motion mechanism and continue rotating past the intermittent motion mechanism. The arm is thereafter biased back into a rotational path of the interface surface such that upon reversal of rotational direction of the rotatable member, the interface surface will reengage the arm and move the intermittent motion mechanism from the second actuation position to the first actuation position.

Patent CA-2282099-A1 (CA)
Inventor: BERNARDINI ALLEN J
IPC: F21Y101/00
Filed: 1999-09-13
Abstract: Disclosed is a lighting system in which the source of light is remotely located from a hollow light guide. The source of light need not be suspended along with the hollow light guide. Instead, the source of light emits light into an optical fiber which can then be focused into the hollow light guide by a light directing element. Advantageously, the arrangement according to the present results in a lighter weight overhead installation, allows the hollow light guide to remain cool over its entire length, eliminates any electrical hazard overhead, eliminates RFI and EMI caused by overhead electrical wiring, and provides for easier maintenance from the floor level. The lighting system provides shock vibration resistance for the light source.

Title: Echo controller with compensation for variable delay networks
Inventor: ROBERT ANDRE J
IPC: H04M7/00
Filed: 1999-09-09
Abstract: The present invention provides a method of and system for controlling and effectively reducing the echo introduced in telephone connections over variable delay networks such as LAN/WAN networks. The invention includes estimation of the round-trip user-to-user delay in the telephone connection. This estimation can be made in a number of different ways, including using timestamps in existing data packets according to a Real-Time Protocol (RTP) or a Real-Time Control Protocol (RTCP) and by sending timestamps in data packets according to an Internet Control Message Protocol (ICMP). The invention further includes determination of an echo control target for the telephone connection based upon the estimated user-to-user delay. This target represents the total amount of echo control required to limit the probability of objectionable echo to less than a predetermined threshold. The amount of echo control required increases as the length of the estimated user-to-user delay increases. The invention further includes determination of the minimum amount of signal-dependent loss required to supplement the acoustic echo cancellation in order to reach the determined echo control target. Then, in the invention, the determined amount of signal- dependent loss is applied to the telephone connection to effectively reduce echo based upon the estimated user-to-user delay.

Title: System and method for implementing call waiting functions over a network
Inventor: BAJZATH JAMES A JR
IPC: H04M3/533
Filed: 1998-05-20
Abstract: System and method for implementing call waiting functions over a network architecture which includes a public switched telephone network (PSTN) (110) and the Internet (120). The call waiting system allows a user (105) to receive incoming call information from a third party without interrupting an active connection with a second party, such as an Internet Service Provider (ISP) (115). When the user attempts to connect to the ISP (115), a call waiting service is activated at a service control point (145) connected to the PSTN (110) and the user is notified about an incoming call attempts made after the user establishes a successful connection with the second party. Meanwhile, the third party caller has the option of leaving a voice mail (150) message for the user (105). If the user (105) is actively connected to the Internet (120), a call waiting Internet server can be used to provide the incoming call information to the user's computer terminal (105). The call waiting system further allows the user (105) to answer incoming calls in real-time when connected to the Internet (120) and return unsuccessful incoming call attempts at a later time. Thus, Internet users can enjoy an uninterrupted Internet session without missing incoming calls. The call waiting system is configurable for non-Internet applications for allowing receipt of incoming call information without interruption an active telephone connection.
