Sealed package that includes a formed plastic container, a shaving cartridge (or other stored unit) in a storage region in the container, and a removable film that covers and is sealed to a sealing surface around an entrance to the storage region. Side walls of the container have retaining structure that protrudes inward and retains the shaving cartridge (or other stored unit). The container has a lip adjacent to and extending from a side wall of the container at an entrance to the storage region to space a user's finger or thumb from the entrance during removal of the cartridge. The removable film has deadfold characteristics which facilitate removal of the cartridge when the film is still partially connected at the rear of the container. A plastic tab is attached to a portion of the film extending beyond the sealing surface of the container to initiate peeling of the film from the sealing surface. The plastic tab is spaced from the formed plastic container by a gap.

A flexible, stackable container for storing a quantity of a product may include a sealed package formed from a single sheet of film and retaining the quantity of the product disposed therein, and a lid fitment attached to a first side of the package. The first side of the package may have an outer first surface of the film and outwardly extending first corner seals formed in the film at the edges of the first side and surrounding the first side of the package. The package may also have a second side disposed opposite the first side and outwardly extending second corner seals formed in the film at the edges of the second side and surrounding the second side of the package. The lid fitment may include a base having a central opening and a lid having a complimentary shape to the base to form a seal therebetween when the lid is closed down onto the base. The base may be sealed to one of the first surface of the first side, to the first corner seals surrounding the first side, or to both, such that a portion of the first surface is accessible from the exterior of the container when the lid is separated from the base of the lid fitment.

A package having fluid-filled chambers that form a line of contact that seals the package. The package generally defines an interior cavity accessible through an opening. Opposing portions of the opening may include at least one fluid-filled chamber to seal the package. The chamber may be held in sealing contact with an opposing structure or with each other by fastening means that hold the opposing portions together. In another embodiment, opposing chambers themselves may interlock to maintain sealed contact. The package may include an auxiliary opening so that an end user can fill the package with articles of the user's choice. The auxiliary opening can be sealed at least over a portion of its length. In another embodiment, first and second compartments are isolated by the fluid-filled chamber seal, with the seal being selectively breachable to enable transfer of product from the first to the second compartment.

An angular velocity sensor has two masses which are laterally disposed in an X-Y plane and indirectly connected to a frame. The two masses are linked together by a linkage such that they necessarily move in opposite directions along Z. Angular velocity of the sensor about the Y axis can be sensed by driving the two masses into Z-directed antiphase oscillation and measuring the angular oscillation amplitude thereby imparted to the frame. In a preferred embodiment, the angular velocity sensor is fabricated from a bulk MEMS gyroscope wafer, a cap wafer and a reference wafer. In a further preferred embodiment, this assembly of wafers provides a hermetic barrier between the masses and an ambient environment.

A stick-on, flexible peel and seal, wet wipes package includes a flexible package body having a front surface, a rear surface and an internal space sized to contain a plurality of removable wet wipes. An elongated opening extends through the package body to the internal space for accessing and permitting dispensing of the removable wet wipes. A substantially self-closing, resealable label flap is positioned on the front surface of the package body to cover the opening formed therein. The label flap has a bottom surface provided with a sealing adhesive that creates a seal entirely around the periphery of the opening and permits repeated application and removal of the label flap relative to the package body. The label flap further has a starting tab non-adhesively positionable in contact with the front surface of the package body. An adhesive layer structure is provided on the rear surface of the package body for adhering the package body to a support surface. A removable peel-off release layer structure covers and protects the adhesive layer structure prior to use thereof. The package body and the adhesive layer structure are removable from the support surface following emptying of the wet wipes from the package body.

A coolerless photonic integrated circuit (PIC), such as a semiconductor electro-absorption modulator / laser (EML) or a coolerless optical transmitter photonic integrated circuit (TxPIC), may be operated over a wide temperature range at temperatures higher then room temperature without the need for ambient cooling or hermetic packaging. Since there is large scale integration of N optical transmission signal WDM channels on a TxPIC chip, a new DWDM system approach with novel sensing schemes and adaptive algorithms provides intelligent control of the PIC to optimize its performance and to allow optical transmitter and receiver modules in DWDM systems to operate uncooled. Moreover, the wavelength grid of the on-chip channel laser sources may thermally float within a WDM wavelength band where the individual emission wavelengths of the laser sources are not fixed to wavelength peaks along a standardized wavelength grid but rather may move about with changes in ambient temperature. However, control is maintained such that the channel spectral spacing between channels across multiple signal channels, whether such spacing is periodic or aperiodic, between adjacent laser sources in the thermally floating wavelength grid are maintained in a fixed relationship. Means are then provided at an optical receiver to discover and lock onto floating wavelength grid of transmitted WDM signals and thereafter demultiplex the transmitted WDM signals for OE conversion.
