Publication number: 20160265753Abstract: A lighted marker for driveways, sidewalks and other various uses. The lighted marker includes a loweer housing and an upper housing. A module including an LED coupled to a battery and a circuit adapted to energize the LED is received in the lower housing through an opening. The upper housing fits over the lower housing preventing water from entering the opening. Alternatively, the module is rigidly secured to the upper housing. The upper housing includes a translucent plastic surface surrounding the LED and viewable from a 360° field of view. The LED lights the translucent surface and the upper housing surface can thereby be seen with night adjusted eyes. The lighted marker is adapted to fit on and preferably be demountably mounted on a fiberglass rod shaped stake which is adapted to be driven into the ground. An umbilical cord is attached between the stake and the lower housing.Type: ApplicationFiled: February 23, 2016Publication date: September 15, 2016Applicant: Jenesis International Inc.Inventors: Bradford B. Jensen, Kim I. McCavit

Patent number: 8284063Abstract: An apparent motion detector is provided with multiple response levels at differing degrees of sensitivity. The motion detector is based on use of a pyroelectric infrared sensor and conventional circuitry which generates an output signal the strength of which reflects transient temperature changes occurring within a field of view and distinguishable from background heat levels. The detector's response varies with the strength of the signal using a plurality of LED's which emit different colors or are driven at different intensities. The system generally will have a field of view defined by a lens system which is translucent to visible light and transparent to infrared. The lens system doubles as a back screen projection system for display of the indicator light.Type: GrantFiled: February 9, 2009Date of Patent: October 9, 2012Inventors: Bradford B. Jensen, Kim I.

Patent number: 7828462Abstract: A decorative, imitation candle effectively simulates a lighted wick in a darkened environment by location of a light source at the tip of an imitation wick. The light source is provided by an LED located at the tip of the wick for direct viewing in order to obtain maximum brightness and high contrast to an observer in a darkened environment. The light source and its support structure are incorporated into the imitation wick so that they do not detract from the imitation candle's realism when the imitation candle is viewed from the side or from above under higher ambient lighting.Type: GrantFiled: April 10, 2006Date of Patent: November 9, 2010Inventors: Bradford B. Jensen, Roger D. Bentley, Kim I. McCavit

Patent number: 7741597Abstract: A motion sensor incorporates an internal light source, typically a super bright LED and an optical projection system visible to an observer standing in the motion sensor coverage zone(s) to simplify orientation of the sensor on installation. A multi-lens system or an arrangement of small windows in front of the LED projects a visible light pattern that mimics the detection pattern of the motion sensor to an observer standing in the detection zone and looking at the sensor.Type: GrantFiled: October 28, 2008Date of Patent: June 22, 2010Assignee: Jenesis International Inc.Inventors: Bradford B.

Patent number: 7360935Abstract: A decorative, imitation candle includes a simulated wick which generates the appearance of an open flame in a darkened environment. A light pipe is located at the expected location of the wick. The exposed end of the light pipe has a tip which produces a point like a light source with a glare effect to darkness accommodated eyes when the device is illuminated. The glare is interpreted as an open flame without the need for a flame shaped terminating structure which is visible when the imitation candle is unlit.Type: GrantFiled: March 31, 2005Date of Patent: April 22, 2008Assignee: Winvic Sales, Inc.Inventors: Bradford B.

Patent number: 7118243Abstract: An imitation candle having an exterior wax shell and an interior illumination source is structured to reduce cracking of the exterior wax shell by incorporating a bonding layer into a central cavity in the shell between the interior illumination source and the wax shell. The bonding layer terminates well spaced from terminal edges of the shell to transfer stress between the illumination source and the shell caused by differing coefficients of thermal expansion to points removed from edges of the shell to retard crack genesis.Type: GrantFiled: March 16, 2004Date of Patent: October 10, 2006Assignee: Jenesis International, Inc.Inventors: Kim I.

Patent number: 6747275Abstract: A motion sensing system is disclosed having a housing or mounting, a sensor, a shield and a cover. A spacer and a printed circuit board may also be included. The cylindrical shaped sensor is placed within the cup shaped shield with the spacer disposed between the sensor and the printed circuit board. The shield and the printed circuit board are then fastened together. Next, the bottom or nose of the mounting shield is placed into the dish shaped cover and the combination is fastened to the housing with the cover extending into an opening in the bottom wall of the housing. The system allows a downward looking motion sensing capability in addition to the typical forward sensing capability which may also be installed in the housing. The housing may then be connected to a security lighting fixture. An even simpler version is a motion sensing system having a simple mounting for a two transducer PIR sensor where one of the transducers is covered and a Fresnel lens is absent.Type: GrantFiled: November 1, 2001Date of Patent: June 8, 2004Assignee: Desa IP, LLCInventors: William C.

Patent number: 6616308Abstract: An imitation candle is made from a translucent material having light transmissive properties similar to paraffin. The imitation candle is shaped to appear reduced by burning. An LED, or similar high intensity light source, is set in a cavity within the imitation candle. The LED preferably produces amber light to better resemble the color of candle light. The imitation candle diffuses the light emitted from the LED to create a warm, natural looking glow. Light emission levels from the LED are varied in a pseudo-random manner to simulate the flicker of candle light.Type: GrantFiled: August 14, 2001Date of Patent: September 9, 2003Assignee: Jenesis International, Inc.Inventors: Bradford B.

Publication number: 20030035291Abstract: An imitation candle is provided having a body made from a translucent material having light transmissive properties similar to paraffin. The body is shaped to resemble a candle that is reduced by burning. An LED, or similar high intensity light source, is set in a cavity enclosed within this material. A color, such as amber, is selected for the LED to produce a light similar to the color of candle light. The material diffuses the light emitted from the LED to create a warm, natural looking glow. Light emission levels from the LED are varied in a pseudo-random manner to simulate the flicker of candle light.Type: ApplicationFiled: August 14, 2001Publication date: February 20, 2003Inventors: Bradford B.

Patent number: 5626417Abstract: A motion detector housing assembly is adapted to be integrated into a decorative coach lamp. The motion detector housing assembly includes a motion detector housing and a carrier assembly which may be configured in a manner to be similar to a decorative housing normally disposed on the top or bottom of the coach lamp assembly. The motion detector housing may be formed with upper and lower housing portions; together which form a generally frustro-conical configuration to match the configuration of a decorative housing disposed on the top or bottom of a lamp assembly. The lower housing portion is formed with an annular window. An important aspect of the invention is that the Fresnel lens member is configured in a generally cylindrical shape. As such, the optics of the system are improved and, in addition, decouples the lens design from the design of the lower housing portion. In order to protect the lens member a plastic lens cover is provided.Type: GrantFiled: April 16, 1996Date of Patent: May 6, 1997Assignee: Heath CompanyInventor: Kim I. McCavit
