Abstract: According to the invention there is in conjunction with a pneumatic tire having a central tread, one or more radially-extending belt(s) disposed radially inwardly of the tread and an innerliner disposed radially inwardly of the belt. Apparatus for mounting an electronic tag (40) within the tire is characterized by a patch (70) having a first side (72) for mounting against the innerliner of the tire; a second arcuately-shaped side (73) and an internally threaded member (71); and an externally threaded member (64) having a portion extending from a side (74) of the tag and threadable into the internally threaded member of the patch.

Abstract: Method and apparatus for conserving energy in a battery powered tag which comprises a battery, one or more sensors, and a transmitter. The tag may be used in a pneumatic tire monitoring system which senses and transmits tire pressure and temperature readings. The method fundamentally comprises: hibernating between transmissions by the transmitter; and reading at least one of the sensors after each of a plurality of sleep periods while hibernating. A hibernation period may be ended if one of the sensor readings, preferably tire temperature, is very low, and at least one of a plurality of qualification criteria is met.

Abstract: Provided is a method of monitoring conditions of a pneumatic tire comprising a central tread, one or more belt(s) disposed radially inwardly of the tread and an inner-liner disposed radially inwardly of the belt(s), the belt(s) having a side edge. An electronic tag and associated condition sensors are disposed within the tire. The method includes: sensing a first temperature which is temperature of the tire inner-liner adjacent to the bet edge with the electronic tag; sensing a second temperature which is the air temperature within the tire with the electronic tag; and sensing air pressure within the tire with the electronic tag.

Abstract: Method and apparatus for conserving energy in a battery powered tag which comprises a battery, one or more sensors, and a transmitter. Preferably, the tag is used in a pneumatic tire monitoring system which senses and transmits tire pressure and temperature readings. The method fundamentally comprises: hibernating between transmissions by the transmitter; and reading at least one of the sensors after each of a plurality of sleep periods while hibernating. Additionally, the sensors, and an analog-to-digital converter if present, can be enabled after each sleep period but before reading the sensors, and disabled again after reading. Along with reading the sensors, the battery may be tested to determine battery energy level after a specified number of sleep periods.

Abstract: An apparatus for monitoring the condition of a hose (100) including an inner liner (104) and a carcass (106) having at least one ply (108a, 108b, 108c, 108d or 108e) disposed in surrounding relationship with the inner liner (104) and an outer cover (300) about the carcass (106). The monitoring apparatus includes an electronic hose tag (310) connected to the hose (100) for measuring the vibration of the hose. In another embodiment, the hose includes at least one sensing element (112) helically wound about the inner liner (104) and an inner sensing element monitoring circuit (404) with a microprocessor (500) connected thereto for determining whether there is a discontinuity in the inner sensing element (112) and thus a worn through area of the inner liner (104). An alarm signal can be transmitted with transmitter structure (430) to a remote receiver (654).

Abstract: According to the invention there is in conjunction with a pneumatic tire (10′) having an electronic tag (100) mounted therein with a patch (70′) having a first side (72′) for mounting against the innerliner of the tire, a second arcuately-shaped side (73′) and an internally threaded member (71′) extending to the arcuately-shaped side (73′). The electronic tag has a pressure sensor (116) located at the bottom of a tubular shaped air inlet structure (118) opening at an upper surface (122a) of the electronic tag, an internally threaded nut (132) having one end (132a) disposed within the electronic tag (100) and an opposite end (132b) extending outward from the upper surface (122a) of the tag, an externally threaded member (134) threaded into the internally threaded nut (132) and extending through the upper surface (122a).
