  • Publication number: 20150298326
    Abstract: A shaving razor includes one or more heaters held in spaced, adjacent relation to the rear non-cutting edge of at least one blade of the razor. The one or more heaters are in connection with an electric power source, which may be located in the blade cartridge or in the handle of the razor. When the electric circuit is closed and electric current flows through the heaters, the heaters generate heat that is directed between the blades and towards the front cutting edge of the blades in a radiator effect. The heaters serve to warm the blades while also providing warmth to the user's skin for increased shaving performance and comfort. In a preferred embodiment, the heaters are made from a high resistance material, such as Nichrome, for producing heat with maximum efficiency.

  • Publication number: 20150135538
    Abstract: A method and system for regulating current flow in a wet shave razor includes one or more conductive materials, such as metals, in electric circuit connection, wherein each conductive material has unique resistance properties and is used to regulate the amount of current (i.e. heat) flowing to at least one electrically powered component on the blade cartridge, and particularly one or more electrically powered devices/elements on the blade cartridge such as, but not limited to, one or more blades, one or more heating elements, a vibration device, illuminating device (e.g. LED or bulb), gauges, or indicators. The length and thickness of the conductive materials used in the electric circuit further affects the total circuit resistance and, accordingly, the amount of current flowing to the blade cartridge for heating the blades. In other embodiments, the dissimilar material conductors may be used to regulate current flow to alternative electrically conductive components.

  • Publication number: 20140245611
    Abstract: A blade cartridge for a shaving razor contains a series of parallel blades and at least two contact segments as part of an electric circuit connected to the blades at spaced intervals to provide an electric current flow through the blades in a manner that provides more efficient heat distribution across the length of the blades. A radiator effect is created wherein heat produced by the contact segments passes between the blades towards the cutting edge of the blades. The combination of the heat produced by the electric current flow through the conductive blades and the heat produced by the contact segments provides a dual heat process that makes it easier to adjust and control the temperature to a desired stable heat temperature. A thin conductive film may be fitted to be in contact with the ends of the blades to insure conductivity throughout the entire length of each blade.

  • Patent number: 8713801
    Abstract: A blade cartridge for a shaving razor contains a series of parallel blades, and at least two wire conductors of an electric circuit connected to the blades at spaced intervals to provide an electric current flow through the blades in a manner that provides more efficient heat distribution across the length of the blades. The ends of the blades may be held in place by staples that are insulated from the electric circuit. A thin conductive film may be fitted to be in contact with the ends of the blades to insure conductivity throughout the entire length of each blade. A radiator effect of the heated blades causes the blades to become warmer when the blades are placed against the skin surface and air is unable to circulate between the blades. The blades become less hot when removed from the skin and air circulates between the blades.

  • Patent number: 7490509
    Abstract: An aerosol capacity indicator that utilizes a novel and inexpensive display that can be installed in the actuator of an aerosol can to display the amount of product remaining therein. The novel accumulative pressure indicator display is imbedded in the actuator which is attached to the valve of an aerosol can and activated by pressure applied directly by the user in the form of finger contact with the actuator. The total amount of pressure applied to the indicator and transferred to the aerosol valve by means of direct user contact both intermittent and continuous renders a relevant reading equivalent to the amount of product released from the aerosol can without any contact with the actual dispensed material.

  • Patent number: 7437373
    Abstract: A method and system for correlating input data that includes configuration data. The configuration data describes at least one hierarchy including a first hierarchy. Each hierarchy includes at least two nodes. Each node includes a value and is designated as an ontology and point consisting of a unique positive integer. For each hierarchy, a unique relationship number RN is stored in a medium for each pair of parent-child nodes of each hierarchy. RN is a function of X and Y which respectively denote the ontology end point of the parent and child node of each pair of parent-child nodes. Responsive to a query that identifies a measure of correlation between the first hierarchy and other information, the measure of correlation is computed by retrieving and utilizing each stored relationship number of the first hierarchy. Information relating to the measure of correlation is outputted.

  • Patent number: 6817101
    Abstract: A shaving system which provides a continuously heated blade cartridge throughout the shaving stroke is attained by applying a measured amount of electric current to the blade cartridge by means of conductors connected on each side of the blade cartridge and extended in the form of contacts built into the docking end of the cartridge. The electric current is provided by a primary battery which is contained in a waterproof compartment in the shaver handle. The current provided by the battery renders opitimum heat generation in the blades in the cartridge and can be adjusted by means of resistors in series with the battery and the blade cartridge. In order to preserve the battery life, a momentary contact switch can be installed in the shaver handle which enables the user to press and hold the switch only during the shaving stroke. In the alternative, the shaving handle may also contain a rechargeable battery which can be continuously charged by storing the shaver handle in a charging stand.

  • Patent number: 5569556
    Abstract: A battery charge indicator is disclosed which accurately displays the true state of charge or energy remaining in an alkaline battery in which the indicator is installed. An alkaline battery cell utilizes a steel can which contains the active chemical ingredients within and provides the conductive surface for the cathode. When the battery is sealed at the open end with a combination plug and anode, the closed end of the steel can becomes distorted or bulged due to internal pressures which are caused by both the expansion of the cathode material due to electrical discharge of the battery and hydrogen gas which accumulates during shelf life in storage. An increase the amount of hydrogen gas occurring during storage creates a distortion or bulge in the center of the closed end of the can. When the battery has been electrically discharged, the cathode material physically expands inside the can causing distortion to extend to the outer periphery of the closed end of the can.

  • Patent number: 5360682
    Abstract: A battery charge indicator is disclosed which is permanently incorporated into a battery to indicate the state of charge. The indicator includes a compressible chamber such as a blister which is adapted to be installed in a battery as an assembly. The blister chamber is filled with a viscous gel and is exposed to the expandable cathode of the battery. As the battery discharges, the cathode expands thus causing the gel within the chamber to be extruded out through an outlet into a viewing channel in an overlying disk. The amount of gel flowing into the viewing channel is proportional to the amount of expansion of the cathode and, thus, indicates the amount of discharge and, conversely, the remaining life of the battery. A battery charge indicator is also disclosed in which the expansion of the cathode is adapted to apply localized pressure to a disk. The localized pressure applied to the disk causes stretching of the material of the disk, which causes a visual indication of the state of charge of the battery.
