International Classification:

G02B 508

US Classification:

307 101, 359602, 359604, 701 49

Abstract:

A vehicle rearview mirror system suitable for use in a vehicle comprises an interior rearview mirror assembly, at least one control and, preferably, at least one exterior rearview mirror assembly. The interior rearview mirror assembly includes an interior electro-optic reflective element having an electrically variable reflectivity. The exterior rearview mirror assembly includes an exterior electro-optic reflective element having an electrically variable reflectivity. The at least one control at least controls a reflectivity level of the interior electro-optic reflective element, preferably in accordance with a duty cycle of a pulse width modulated signal. The at least one control may further control a reflectivity level of the exterior electro-optic reflective element via a bus system of the vehicle. The control or controls may communicate and/or control an accessory of the vehicle via the bus system of the vehicle. The controls may comprise a control node of a vehicle control network.

Abstract:

A construction apparatus ( ) and method of controlling a construction apparatus from a laser source ( ) made up of a substantially non-rotating beam ( ). The construction apparatus includes a body ( ), a construction tool ( ) adapted to move material, a support moveably supporting the construction tool from the body and a control for guiding movement of the construction tool. A control is provided including a camera ( ) that is adapted to capture an illuminated image that is derived from the laser source. The control determines direction information of the illuminated image with respect to the apparatus at least in part from an output of the camera. The control is further adapted to determine separation information of the spot with respect to the body and a physical relationship between the construction tool and the illuminated image. The construction tool ( ) can be guided with respect to the illuminated image as a function of the direction and separation information and the physical relationship between the construction tool and the illuminated image.

International Classification:

G02B005/08

US Classification:

701 49, 307 161, 359602, 359604

Abstract:

A vehicular control system comprises a rearview mirror assembly and a microcontroller. The rearview mirror assembly comprises a housing and a variable reflectivity electro-optic mirror element. The microcontroller is operable to control the reflectivity of the variable reflectivity electro-optic mirror element. The microcontroller may be operable to control a plurality of accessories of the vehicle via a node of a vehicle control network. The microcontroller may be operable to receive signals from and/or transmit signals to at least one of the accessories via the node of the vehicle control network. The microcontroller may be in communication with a second microcontroller located in the mirror housing or exterior to the mirror housing. The microcontroller and the second microcontroller may be cooperatively operable. The microcontroller and the second microcontroller may be in master/slave relationship.

International Classification:

F21V 2700

US Classification:

362387

Abstract:

A utility emergency light assembly for vehicles, machinery, or the like detachably mounted by a slide coupling to a mounting bracket attached to the vehicle or machine. The light assembly has a compact, space-saving profile and includes a housing having a lamp assembly mounted within a spool journaled in the housing for reeling and unreeling a power cord, enabling movement of the assembly to areas of the vehicle where light is needed. A cap substantially closes the housing and includes a lens located over the lamp assembly. The lamp assembly is sealed within the spool, while the remainder of the housing is open to allow water drainage and to prevent the accumulation of moisture and debris.

International Classification:

G02B 508

US Classification:

307 101

Abstract:

A vehicle control system comprises an industry standard CAN network with a number of nodes distributed around the vehicle for controlling corresponding parts of the vehicle. One such node is located in the housing of the vehicle interior rearview mirror and directly controls the reflectivity of an electro-optic mirror unit, in accordance with the state of at least one ambient light sensor and a remote keyless entry device. The node also communicates via an ISO9141 interface with a number of slave controllers such as a sun-roof control module mounted adjacent a sun-roof and a roof control module mounted in a roof housing. By this means the UCM exercises indirect control of the sun-roof in accordance with the state of a switch, and exercises indirect control of various lamps GEN1, GEN2, FLL and FRL in the roof housing in accordance with the state of switches Gen, FL and FR mounted in the roof housing or, in the case of the lamps GEN1 and GEN2, when a vehicle door is opened.
