Abstract: To improve pedestrian visibility. Provided is a headlight controller connectable to a first headlight and a second headlight spaced apart in a vehicle width direction at the front of the vehicle, the headlight controller including: a rainfall amount detection means installed in the vehicle; and a controller installed in the vehicle, where the controller is connected to the rainfall amount detection means, and the controller carries out control such that when rainfall amount detected by the rainfall amount detection means is equal to or more than a predetermined value, irradiation light from the first headlight becomes relatively darker than irradiation light from the second headlight.

Abstract: Provided is a wireless communication system in which, based on a random access scheme, a transmission opportunity (TXOP) acquired by a wireless access point is granted to a wireless station when performing uplink data transmission from the wireless station to the wireless access point and the TXOP acquired by the wireless station is granted to the wireless access point when performing downlink data transmission from the wireless access point to the wireless station, the system includes a scheduling unit for TXOP granting determining one or more wireless stations having a quality of an uplink data transmission lower than a prescribed value as TXOP responders to which the wireless access point grants the TXOP, and determining one or more wireless stations having a quality of a downlink data transmission lower than the prescribed value as TXOP holders which grant the TXOP to the wireless access point.

Abstract: Methods and systems provide a telephone service with a personal switch box. One aspect of an embodiment of the invention extends use of a telephone number on a Public Switched Telephone Network to mobile terminals by a personal switch box relaying telephone call signals between the Public Telephone Network and an IP-PBX, where the IP-PBX routes the calls between the personal switch box and a cellular phone that is associated with the personal switch box, through a gateway of a mobile virtual network operator the telephone number over mobile wireless network. The gateway may control network bandwidth allocation for the data traffic with the mobile terminals during voice stream data transmission for providing required quality of service.

Abstract: Methods and systems for dynamically controlling per-session throughput and application priority are provided. Said method is under the control of one or more computer systems configured with executable instructions. The method comprises receiving, at a mobile virtual network operator, a request to initiate a data-based application. The request is received from a mobile device that is associated with a data plan that is managed by the mobile virtual network operator. The data-based application is associated with a category of data. The method also comprises evaluating the request at a feedback-based packet control system of the mobile virtual network operator utilizing a speed monitoring module and business rule engine in evaluating the request. The method further comprises allocating data to the data-based application request. The allocation of data is based on a data plan and and/or category of data. Additionally, the method comprises providing the data-based application request to a server.

Abstract: A computer-implemented method for providing data communication between two or more host systems is provided. The method comprises designating a first network as a primary network by updating a routing table, monitoring network connections on the first network channel and a second network channel, transmitting data on the first network channel according to the routing table, detecting termination of network connection on the first network channel, determining to transmit data traffic on the first network channel, modifying the routing table, transmitting data traffic on the second network channel according to the routing table, detecting connection on the first network channel, and in response to the detection of data traffic on the first network channel, measuring a network attribute and comparing against a satisfactory threshold, and selecting the first network channel for data communication if the network attribute value satisfies the threshold.

Abstract: Provided herein are systems and methods for implementing a more secure network client device in connection with the dynamic host configuration protocol (DHCP). Incoming DHCP Offer packets containing configuration information are temporarily collected. Once all incoming Offers are judged to have been received, offers are scored and a winning offer is selected. The winning offer is used to configure the device's network stack.

Abstract: Methods and systems are provided for providing redundancy in data network communications. Data traffic on a first network channel used for the data communication between the two or more host systems can be monitored to obtain one or more attributes associated with the data traffic. Based on the data attributes, it may be determined whether one or more anomalies associated with the attributes exist. If so, the anomalies may be used to determine whether they are indicative of an imminent or current network event or condition. In response to a determination that the one or more anomalies are indicative of the event or condition, a second network channel may be selected for the data communication between the two or more host systems.

Abstract: A speech signal bandwidth compression and expansion apparatus and its method. On the transmitting side, system parameters are extracted from a speech signal by a linear prediction analyzer. A prediction residual signal is obtained by inverse filtering processing by using the system parameters. The prediction residual signal is lowered in sampling rate by a down-sampler and converted to a baseband signal. From the baseband signal, a time series signal is derived by a linear prediction synthesizer. Thereafter, the time series signal is converted to an analog signal and transmitted. On the receiving side, a received signal is subjected to inverse filtering processing to reproduce a baseband signal. The sampling rate of the reproduced baseband signal is raised to derive a time series signal. From the time series signal, a high frequency band component is generated. The high frequency band component is added to the baseband signal to generate an excitation signal.

Abstract: A syringe needle disposer includes a setting section for setting waste syringe needles and a magnetic field generating section for providing a high frequency alternating field to the setting section. When the high frequency alternating field is activated, a magnetic path of the magnetic flux passing through the waste syringe needle set in the setting section is formed, thereby induction-heating the syringe needle to soften the needle and to round its tip and to close an axial hole of the syringe needle. The sharp edge of the softened syringe needle may be blunted by contacting a pressure plate under pressure.
