A radiation therapy system optimized for treating extremities such as the breast has unique geometrical features that enable the system to deliver an accurately located prescribed dose to a target volume while eliminating or reducing the collateral dose delivered to the rest of the patient. The patient lies in a prone position on a rotating, shielded table, with the anatomy to be treated protruding through an orifice in the table into the path of a radiation beam. An optional integral imaging system provides accurate target volume localization for each treatment session. Utilizing the effects of gravity on a prone patient maximizes the separation of a target volume within the breast to adjacent critical structures such as the chest wall, heart and lungs, thereby reducing long term complications not associated with the primary disease. A shielded interface surface between the radiation source and the patient reduces patient dose due to scattered or stray radiation. A shielded enclosure for the radiation sources combined with the shielded interface surface eliminates the need for primary shielding in the room and allows the therapy system to be used in a transportable, mobile facility.

Adaptive cruise control method improves traveling performance and stoppage maintenance performance on an incline. During adaptive cruise control, a gradient of a road is estimated based on a vehicle acceleration and longitudinal acceleration to enable compensation of a resistance torque with respect to the gradient of the road, which prevents deterioration of a traveling speed of a vehicle on an incline. Also, compensating for a brake torque to prevent the vehicle from being pushed rearward when the vehicle stops or starts to go on an incline may prevent deterioration of performance on an incline.

In a motorcycle-use power unit in which a clutch device arranged in a power transmission path between a crankshaft and a drive wheel is housed in a clutch chamber which is defined between a crankcase and a clutch cover joined to a side surface of the crankcase, the maintenance of the clutch control device can be easily performed while preventing a lowering of oil-pressure transmission efficiency between the clutch device and the clutch control device and preventing an increase in the weight of the motorcycle. A clutch control device performs a changeover of engagement and disengagement of a clutch device by controlling the oil pressure applied to the clutch device. Oil passages for connecting the clutch control device and the clutch device with each other are mounted on a clutch cover.

An image forming apparatus that can maintain the accuracy of temperature control of an object to be heated within a predetermined range and avoid adverse effects of contamination of first temperature detection means. The image forming apparatus 1 has a photosensitive drum 14, a heater 901, a thermopile temperature sensor 902, a non-contact thermistor 903, and a control circuit 904. The control circuit 904 controls the heater 901 based on an output signal 902s in a case where the output signal 902s is output earlier in time than the output signal 903s, and informs of a state of the thermopile temperature sensor 902 in a case where the output signal 903s is output earlier in time than the output signal 902s.

A method and system for performing one or more preventative maintenance functions for a data-processing apparatus. One or more notifications regarding daily maintenance functions can be generated in the form of a reminder when the data-processing apparatus begins operation. A history of the maintenance functions performed can be stored in a memory through remote data pushes. An email alert can be generated and transmitted to a user regarding incomplete maintenance functions in order to track the maintenance activities. The data-processing apparatus can be monitored in a consolidated manner and the occurrence of fault information stored and then rapidly retrieved to provide notifications indicative of such maintenance data.

A non-motorized waterfowl decoy device includes a recoil mechanism adapted for use in a front-facing position or a rear-facing position. The recoil mechanism includes a rotatable spindle having a long axis about four times greater than its diameter. The recoil mechanism further includes a elastic drive member adapted to slidably couple into a pair of corresponding slots on the spindle and engage a rear-support post having a u-shaped alignment channel. A pull cord attached to the spindle causes the spindle to rotate and coil the elastic drive member. Positioning the pull cord through a provided aperture on the rear guide-post enables reward-facing operation and, positioning the pull cord through a provided aperture on a front guide posts enables forward-facing operation.

Digitized components are used with an electric musical instrument to save one or more component configurations into one or more presets thereby enabling a user to instantly select the saved component configurations for output. The user can select the saved component configurations using one or more buttons or a pick-up selector switch to instantly change pick-up, tone and volume. In addition, the electric musical instrument is able to produce sound in the event of a power loss.

The infection of a mammalian host by a microorganism can be prevented or treated through the alteration of the C. albicans homologue of the high affinity phosphodiesterase, PDE2, gene and / or the adenylate cyclase-associated protein gene. These methods may be used in the identification, prevention or treatment of microbial infection of mammalian hosts such as immunocompromised or immunosuppressed humans, for example, those having AIDS or undergoing transplantation or anti-cancer therapy.

A method of determining a learning area of injector opening duration according to the present exemplary embodiment divides an entire control area for controlling opening duration of an injector into a learning map area which needs learning and a reference map area which uses an already prepared reference map as is without learning, and a period from a minimum injection time to a minimum linear injection time of the injector is determined as the learning map area, and a period from the minimum linear injection time to a maximum injection time is determined as the reference map area.

Apparatus and method are provided for distributing service domain reachability information across domain boundaries, thereby allowing domain management systems to determine routing for cross-domain services even when the domains have different technologies or administrators. A Service Domain Manager within each domain advertises to neighbouring domains which services it supports. A domain which receives such advertisements forwards the advertisement on to other domains. Each SDM builds a routing information table which specifies the service, the domain, the next hop, and optionally user defined metrics. The routing information table does not include end-point addresses, in order to keep the size of the table manageable. In this way, the NMS of each domain obtains an end-to-end view of service routes.

An engine includes an exhaust gas control apparatus that is configured to store NOx and react NOx with a reduction agent. A control device for the engine includes an electronic control unit. The electronic control unit is configured to: (i) execute a rich spike control, the rich spike control is a control executed to temporarily change an in-cylinder air-fuel ratio from a leaner air-fuel ratio than the stoichiometric air-fuel ratio to the stoichiometric air-fuel ratio or a richer air-fuel ratio than the stoichiometric air-fuel ratio, and (ii) vary an overlap amount of an intake valve and an exhaust valve such that the overlap amount is less during execution of the rich spike control than during non-execution of the rich spike control, in an operation range where a pressure of the intake port becomes higher than a pressure of the exhaust port.
